What is the structure of steel? This is a question many people wonder about. Steel is known as an alloy of iron and carbon, along with a number of other chemical elements (Si, Mn, P, S, Cr, Ni, Mo, Mg, Cu,...), in which the carbon content is less than 2%. These chemical elements are flexibly adjusted to increase or decrease hardness, ductility, and oxidation resistance according to different types of steel. Because of this diversity, there are more than 3,000 types of steel in the world.Different types of steel will have different carbon ratios, the carbon content usually ranges from about 0.02% to 2.14%, depending on the weight. The higher the carbon ratio, the harder the steel is, but it is brittle and easy to break.Steel has very high applicability and is commonly used in many industries. At the same time, steel also symbolizes the speed of technological development in countries around the world, including Vietnam. Therefore, the steel manufacturing industry has always received special attention and investment from our government.Wire rod is used a lot in life todayCharacteristics and chemical composition of steel materialsWhat is steel? We have answered in the above section. Below, join AG真人游戏 Steel to learn more about the properties and chemical composition of steel.Characteristics of steelDuring the steel making process, dividing the ratio of carbon and iron can create many types of steel with different properties. Therefore, steel refining will not only produce a product of the same type but also depend on the needs and purposes of the steel being refined.Normally, steel has basic properties such as plasticity, hardness, durability, resistance to oxidation, elasticity, and weldability. These properties of steel are determined by chemical elements such as carbon, iron, nitrogen, and sulfur.The ductility of steel depends on the carbon content of the steel. The increased carbon content results in a harder and stronger material with reduced ductility. Conversely, the low carbon in steel, the more flexible and malleable.Steel material has high mechanical properties and has many types with many different uses, so it is a material used in many different industries: mechanical manufacturing, construction, shipbuilding,... In general, the most important properties of steel are its corrosion resistance and high durability.Stainless steel is highly resistant to corrosionChemical composition of steel materialsWhat is steel made of? What chemical composition are steel materials? Let's learn about the chemical composition of steel with us below:Steel is an alloy, whose main components are iron and carbon. In addition, when producing, different elements will be added in certain proportions, thereby creating different types of steel depending on the intended use. Commonly added elements include manganese, phosphorus, silicon, chromium, nickel,... These elements are added to improve the quality, hardness and elasticity of steel.How is steel classified? Common types of steel in constructionHow is steel classified?What is steel of and what are its classifications? Steel is a material with extremely diverse classifications. Below, we will learn about some of the main classifications.Classification based on chemical compositionThis is an important classification because chemical composition is an important factor affecting the characteristics and properties of steel. Usually, they are divided into two main types: carbon steel and alloy steel.Carbon steel: Carbon steel is a type of steel whose main components are iron and carbon other elements are negligible. Although carbon steel only has two main elements, it can be prepared in countless ways with many uses by reducing the carbon content in the steel, depending on the purpose of use.Alloy steel: Alloy steel is a type of steel whose main components are iron and carbon combined with other chemical elements (copper, manganese, nickel,...), with a total content of additional elements ranging from 1.0% to 50% of total amount. Compounds are added to improve steel quality as well as elasticity, ductility, strength and oxidation resistance. Thanks to those alloying elements, alloy steel in general has outstanding advantages compared to carbon steel.Carbon steel pipeClassification by useDepending on different purposes, steel will be divided into:Structural steel: Usually has high durability, toughness, bearing capacity, and large load capacity and is specialized for production, manufacturing, and use in the construction, assembly, and machine manufacturing industries, as well as mechanical engineering.Tool steel: Usually has high hardness, durability, good strength, and corrosion resistance.

For example, there are types such as carbon steel, alloy steel, stainless steel, and tool steel.Second, the classification of steel grades can be based on the finishing method, such as hot-rolled coil, cold-rolled coil,...Third, it can also be classified based on the production method, including types such as production by EAF furnace, BOF furnace,..Fourth, crystal structure is also an important criterion when determining steel grades, with types such as ferritic steel, perlite steel, and martensite steel.Finally, mechanical strength also plays an important role in steel grade classification, with properties such as tensile strength, yield strength, elongation, curvature, and weld strength being closely considered.Standards for steel grades and how to read steel gradesStandards for steel gradesSteel grade production also requires its own standards, with each production standard having different steel grade types. Below, AG真人游戏 Steel would like to share some popular standards for steel grades on the market today.Steel grade according to Vietnamese standards - TCVNTCVN is the most commonly applied standard in the steel manufacturing industry. Among them, there are 4 common standards: TCVN 1651-1:2008, TCVN 1811_2009 (ISO 14284-1996), TCVN 6287_1997, and TCVN 7937-1-2013. For each different type of steel, there will be different standards, specifically:TCVN 1651-1:2018 for plain round steel barTCVN 1651-2:2018 for rebar steelTCVN 1651-3:2008 for welded wire mesh rolls and panelsTCVN 1811:2009 for steel and cast ironTCVN 6287:1997 for steel bars for concrete reinforcementTCVN 7937-1:2013 for steel for prestressed concrete reinforcementVNSteel's steel is produced according to TCVN standardsSteel grade according to Japanese standards - JISJIS stands for Japanese Industrial Standards. This standard was developed by the Japan Standards Federation. Besides the 5S standards, JIS represents professionalism in manufacturing and production. It has contributed in no small part to the most reliable and prestigious international standard system today.The general symbol of JIS Japanese standard products is JIS Gxxxx. In particular, JIS is the symbol name of the JIS industrial standard. G is the letter representing the steel industry, xxxx is the symbol for each specific item.Steel grade according to Russian standardsAlso similar to Vietnamese standards in designation, steel grades in Russian standards are abbreviated as CT, followed by numbers from 0 to 6. These numbers represent the chemical and mechanical properties of the steel. When the number of symbols is large, it shows that the proportion of carbon in the alloy is higher, and therefore the strength of the steel is greater. For low-carbon steel, less than 0.15%, it will be denoted CT0.To classify steel grades according to Russian standards. The corresponding numbers are often found at the end of the steel grade. Level 1 is not recorded. In front of the steel grade, write the corresponding steel groups A, B, and C.Steel grade according to American standards - ASTMIn American standards, the process of coding and determining the properties of metal materials is extremely strict, especially steel. This standard, which requires the use of many complex steel grading systems, makes an important contribution to defining their quality and application in many industrial sectors.ASTM is a standard issued by the American Society for Testing and Materials. It is considered a tool to evaluate, specify, and classify the chemical, mechanical, and metallurgical properties of each type of steel. The scope of application is in the production of mechanical parts, industrial parts, construction elements, and accessories related to them.Steel labeled with the ASTM standard means that the steel meets exactly the criteria specified in the standard. Some popular ASTM steel grades today are: A29, A27, A36, A53, A304, A355, A392, A400, A575, A689, A914, and A920.Hoa Phat's construction steel grade symbolHow to read steel gradesYou already understand the symbols of steel grades, so how to read steel grades can also be found below.Steel round barFor round steel, steel grades are often denoted with both letters and numbers. Lowercase letters represent typical symbols of national standards, and the numbers behind them represent the bearing strength of the steel. This notation depends on the standards of the factory that produced the steel.If that factory uses Japanese standards for production, it will be denoted SD, in which S stands for steel and D stands for deform. If using a mark according to Vietnamese standards for production, the symbol is CB, with C standing for durability level, and B is the symbol of the steel group. If that factory uses standards from the US or Europe, the symbol is usually grade, where grade means type.For steel plates, shaped steel and steel hollow sectionFor this type of steel, there will usually be no symbols on the steel product. That steel grade will come with paperwork, or we will have to cut a sample for testing to know how much that steel grade is worth.In particular, steel hollow sections are one of the most commonly used steel materials today. Therefore, memorizing steel grades is one of the most accurate and effective ways to choose steel hollow sections for you.

In the manufacturing process, determining the stainless steel melting point plays a crucial role in predicting and analyzing the crystal structure and physical properties of the finished steel product thereafter. Identifying the ideal temperature for the melting process is a top concern for businesses when they need to identify suitable materials for their projects.In today's article, let's explore the definition and significance of the melting point of stainless steel with AG真人游戏 Steel. Additionally, we'll compare its melting point with other popular types of steel currently available in the market.Determining the precise melting point of stainless steel is a necessary stageRoles of stainless steel melting point to mechanical propertiesStainless steel is a special type of steel known for its high corrosion resistance, achieved through alloying with elements such as chromium, nickel, and molybdenum. During production, the stainless steel melting point is the specific temperature at which this type of steel transitions from a solid to a liquid state during heat processing. Determining the melting point of stainless steel is crucial for manufacturers as it directly influences the operations of melting and steel casting.Specifically, the melting point of stainless steel is considered a prerequisite condition to ensure that the material does not undergo structural deformation during processing at high temperatures. Additionally, the melting point helps manufacturers identify the ideal temperature for subsequent casting, forging, or welding processes. However, after stainless steel has undergone hardening and preliminary processing steps such as rolling or forging, the melting point no longer holds significant importance for engineers or manufacturers.The melting point help identify optimal temperature for subsequent manufacturing processesThe ideal temperature for grades of stainless steel melting point Stainless steel is a type of alloy steel comprising multiple metal elements combined together, each of which typically has its own melting range. This leads to the stainless steel melting point often not falling within a fixed value; instead, it occurs within an expanded temperature range. Most alloying elements added to stainless steel often have higher melting points compared to iron, with chromium (Cr) specifically having a melting point of 1890掳C while iron reaches 1535掳C.1375掳C to 1450掳C is the accurate temperature range for the stainless steel melting pointTherefore, for stainless steel, the melting point is usually higher than other types of steel due to the presence of chemical compounds such as chrome, nickel, and molybdenum. Typically, the stainless steel melting temperature can range from approximately 1375掳C to 1450掳C, depending on the specific composition of each type of stainless steel. Its stability and excellent heat resistance are crucial factors that make it suitable for a wide range of high-intensity applications.Table of melting temp of stainless steel gradesStainless steel is a special type of steel with various grades ranging from austenitic stainless steel (such as 304, 316, and 317) to ferritic stainless steel, martensitic stainless steel (410 and 420),... All of these steel grades have different thermal expansion coefficients and melting points due to differences in chemical composition and mechanical properties of stainless steel. Below is a table listing the melting points of various types of stainless steel:The melting points of steel types and other metalsList of factors affect the melting temp of stainless steelAt high temperatures, many materials, including stainless steel, begin to significantly reduce their tensile strength and hardness even before reaching the melting point. A typical case with stainless steel, this material can retain 100% structural integrity at 870掳C (1679掳F), but at 1000掳C (1832掳F), it loses 50% of its tensile strength.Exposure to high temperatures not only makes stainless steel prone to deformation but also affects the protective oxide layer of stainless steel, increasing the risk of corrosion and rusting in the future. In summary, during the heating process, even if the stainless steel melting point has not been accurately reached, it can still be damaged when exposed to high temperatures. Therefore, fabricators need to regularly monitor and control the stainless steel melting temperature to ensure structural integrity.High temperatures and amount of impurities in the structure directly affect to stainless steel melting pointIn steel composition, elements other than the main constituents (iron and carbon) are considered an impurity, and the amount of impurities directly affects the melting rate of the steel. Stainless steel, with the presence of various impurities such as nickel, chromium, and molybdenum, tends to have a slower melting rate compared to other types of steel. Therefore, the stainless steel melting point can vary depending on the amount of impurities in the structure; the melting point increases as the amount of impurities decreases and vice versa.The difference between melting point of stainless steel 304 & 316304 and 316 are the two most common types of stainless steel in today's industry. Both originate from Austenitic stainless steel with a face-centered cubic crystal structure. This structure is considered unique as it remains unchanged at all temperatures from freezing to the precise stainless steel melting point. Although both types of steel share the same crystal structure, their chemical compositions differ, particularly in the amounts of nickel, molybdenum, and other elements.The melting point of stainless 304 is 1400掳C while 316 is approximately 1375掳CThe melting points of stainless steel 304 and 316 have slight differences.The melting point of stainless steel 304 is around 1400-1450掳C (2552-2642掳F), while the range of stainless steel melting temperature 316 is approximately 1375-1400掳C (2507-2552掳F). The difference in chemical composition and melting point between stainless steel 304 and 316 makes each type suitable for distinct applications.Finding cost-effective options for stainless steel at AG真人游戏 SteelUnderstanding the precise stainless steel melting point plays a crucial role in enabling manufacturers to carry out machining operations such as casting, forging, or rolling smoothly thereafter. Failure to control and monitor temperatures regularly during heat treatment can adversely affect the crystal structure, thereby reducing the quality of the final output of stainless steel products.Therefore, selecting reputable factories for stainless steel production is essential if you are in need of purchasing this product for your project.

AG真人游戏 Steel has detailed a comparison of steel vs stainless steel, including properties, applications, costs and many other important factors.Stainless steel and steel are alloy steels with unique strengths and applications. Understanding the difference between these two types of steel is fundamental to choosing the right material for the project. The difference between steel and stainless steel lies in their composition and propertiesGeneral introduction to steel vs stainless steelsSteel is an alloy of iron and carbon, combined with a number of other elements such as nickel, molybdenum, manganese, titanium,... to determine the mechanical properties. Steel is a metallic material so it has metallic luster, strong electrical and thermal conductivity. At temperatures of 500-600 degrees Celsius, steel becomes ductile and its strength decreases. At -45 degrees Celsius, steel is brittle and prone to cracking.Stainless steel is also a type of alloy steel commonly used in life. The difference is that they have a minimum chromium content of 10.5 wt% and a maximum of 1.2 wt% carbon. Thanks to this special composition, stainless steel has outstanding resistance to corrosion and rust.Stainless steel is generally stronger than conventional steel in various applications due to its unique composition and propertiesLearn about the difference in properties of steel and stainless steelSteel vs. stainless can be based on the features in property of steel below:Corrosion resistanceCompared to conventional steel, stainless steel has superior corrosion resistance thanks to its 10.5% chromium content. When exposed to outside air, chromium creates a layer of chromium oxide (III) that cannot be seen with the naked eye, so the surface of stainless steel is always shiny. Molybdenum in stainless steel is also highly resistant to corrosion, even in acidic environments.StrengthIs stainless steel stronger than steel? Steel is a material with high tensile strength ranging from 400 - 1882 MPa, good bearing capacity. Meanwhile, the tensile strength of stainless steel is about 518-827 MPa, with standard strength, heat resistance and hardness.Therefore, while stainless steel can be strong in some applications, high-carbon steel can have a higher tensile strength than some types of stainless steel.DuctilityThe carbon content in steel is no more than 2.14% by weight. The more carbon in steel, the higher the hardness and durability of the steel. While stainless steel only has a maximum of 1.2 wt% carbon, it is more flexible and easier to shape than conventional steel.AppearanceStainless steel has a high chromium content, so it has a smooth, shiny appearance. For applications requiring high aesthetics, stainless steel is a more ideal material than conventional steel.MagnetismUsually people still think that stainless steel is a non-magnetic or non-magnetic material. In fact, the structure of the metal will determine whether stainless steel is magnetic or not. Of the 4 groups of stainless steel, only the Austenitic group is non-magnetic and the remaining 3 groups are all magnetic. Therefore, if the stainless steel you are using belongs to the magnetic Martensitic, Ferritic or Duplex groups, then when tested with a magnet, the steel will still be attracted like ferromagnetic materials.What is the difference between steel and stainless steel?Steel vs stainless steel: which is the better cost?The input materials of steel are mainly iron, carbon and some other chemical elements, while the chromium content in stainless steel is very high, further increasing the cost. The steel production process is also simpler than stainless steel, optimizing energy and labor costs. In addition, processing and manufacturing stainless steel requires high expertise and complexity, leading to the price of finished stainless steel being more expensive than steel products.How is the difference between the applications of steel vs stainless steelStainless steel stands out with its resistance to corrosion, rust and extremely high aesthetics, so it can work in many harsh environments such as the petrochemical field, aerospace, marine,... Stainless steel does not contain chemicals harmful to users' health, so it is an ideal material for use in the medical and food industries.Meanwhile, steel has high mechanical properties, has many different types and uses, so it is applied in a variety of industries such as construction, mechanics, shipbuilding,...Conclusion on the most distinctive differencesFactorsSteelStainless steelKey raw materialsMade of iron, carbon and some other metalsMade of iron, chromium and some other metals.StrengthHigh tensile strength, susceptible to corrosion and rust in natural conditions, low heat resistanceLower tensile strength, easy to shape, extremely good resistance to corrosion and rust.ApplicationUsed in civil construction, equipment, automobile components,...Used in the fields of medicine, food, furniture, chemicals,...AG真人游戏 Steel - Bringing the best Vietnamese steel import experienceOnce one of the smallest economies in Southeast Asia, Vietnam has now become leading economic markets in the world, especially in the field of metal import and export.

AG真人游戏 Steel sends you information about this revolution in the article below!The steel industrial revolution is a step in the development of human civilizationWhen did the steel industrial revolution begin?When was steel first made? Steel was first manufactured in ancient times, but in this period, the steel industry was located in places with raw materials, electricity, and running water to facilitate the production process. However, it was not until the 1850s that the history of the steel industry began to develop. In 1857, thanks to the development of the Bessemer converter by Henry Bessemer, steel was mass produced. Since then, steel has become a staple of the world's industrial economy and soon replaced iron in the construction industry.The steel industrial revolution marked a leap forward in the history of human civilization. The flexibility and sturdiness of steel today is not only used in construction but is also commonly used in many other industries.What was steel used for in the industrial revolutionThe steel industry has opened new doors for human civilization. The steel history timeline has marked the development of the world economy. With its advantages and versatility, steel is used in many different industries. Below are some applications of steel in the industrial revolution.Steel is widely used in construction architecture. After gradually changing iron in the construction process, steel seems to open a new era of skyscrapers and modern architectural works. Iconic skyscrapers represent famous architectural works today, such as the Eiffel Tower, Burj Khalifa in Dubai, Shanghai Tower in China, and Lotte World Tower in Korea. It's all a testament to the transformative power of steel in building architecture.Eiffel Tower - A famous structure made of steelSteel is used in transportation The steel industrial revolution plays a huge role in the development of transportation infrastructure. The advent of the railway industry saw a transformation with the widespread adoption of steel rails, allowing trains to travel at higher speeds and carry heavier loads. Besides, steel also contributed to the construction of iconic steel bridges, including the Brooklyn Bridge and the Golden Gate Bridge. These are two bridges that demonstrate the outstanding strength of steel in building modern transportation routes. In addition, steel in the industrial revolution was also used to build ships, cars, and aircraft.Steel and industrialization The steel industrial revolution ushered in a new civilization in human history, and steel played a central role in driving this enormous change. Steel is associated with the industrialization process as it gradually replaces iron to become the main component in the construction process.

This also requires steel manufacturing businesses to find ways to reduce emissions and increase sustainability in the production process.New technology When technology continuously changes and develops, it directly affects the steel production industry. This forces steel manufacturing businesses to keep up with new technology to improve product quality. However, along with new technology comes the cost of investing in production lines, which is also a big barrier for steel manufacturers.Future direction of the steel industryThe steel industrial revolution has brought the steel industry to develop dramatically, becoming a key sector of the world economy. Looking at the current situation of the iron ore market and steel industry, one of the future directions that the steel industry wants to aim for is the development of the green steel industry. When governments around the world introduce many new regulations as well as carbon taxes to improve the environment, green steel production is a goal that is both vital to the steel industry and contributes to limiting warming.Currently, many of the world's leading steel manufacturers have started producing green steel or have set goals in the next few decades to no longer use fossil fuels. Vietnam's steel industry also aims to be carbon-neutral by 2050. Green steel is not only a trend but also a necessary step to protect the environment and create a sustainable steel industry in the future.Green steel production is gradually becoming a trend in the futureAG真人游戏 Steel - The future of Vietnam's steel industryIn recent years, Vietnam has grown to become one of the world's major crude steel production powers.

The importance and significance of steel in today's world cannot be denied. Steel is considered the spine of a modern, civilized, and progressive society. But when was steel invented? How is the development process?In the article below, AG真人游戏 Steel will help you learn about the history of the formation and development of the steel industry.When was steel invented? Let's find out belowWhen was steel invented?It is difficult to have an exact answer to the question 鈥淲hen was steel invented?鈥� Many people think steel appeared at the beginning of the industrial revolution, but it appeared a long time ago. After the Iron Age, from the 13th century BC, steel was invented by heating iron in a hot fire, at which point the iron would become harder and stronger. Since then, people have found traces of steel in many different cultures and territories around the world, and usually only a few shapes of steel are made for use in everyday life.However, the early invention of steel had a wide range of carbon in the metal, from less than 0.1% (low carbon steel) to 1% (high carbon steel), which could lead to steel with a higher carbon content being very brittle. This brittleness can be reduced by tempering the steel, which is a form of heat treatment that was used in Egypt as early as 900 BC.Later, in the mid-1850s, Henry Bessemer, the British inventor first created a method to produce steel in large quantities. Since then, steel has been produced based on the Bessemer process. The operating principle of this process is to heat iron ore and other chemicals, then blow oxygen into the blast furnace to separate impurities from the metal mixture. This method is similar to the steel production method we are using today.Bessemer steel making processUntil now, the creation of steel was essential to human life. Steel is always ahead of the game and is commonly used in construction and many different industries. There are a number of reasons for this, from the variety of shapes it can be formed into to its relatively low strength and weight compared to other metals.Development stages of the steel industryTo continue answering the question, when was steel invented? What is the development history of steel? Let's study the development stages of the steel industry below.Early stageThe steel industry began to form in the late 19th century under the leadership of two leading developed countries, China and India. During this period, the steel industry was often produced manually, by forging or hand casting. This is the initial stage of the steel industry, when production methods have not been automated and the production scale is still small.In 1856, the birth of the Bessemer furnace helped steel production happen faster with cheap costs and large output. By 1865, Andrew Carnegie brought the Bessemer process to America, and from then on, America suddenly rose to the top of the steel industry.Historical period that saw a rise in steel makingAfter its infancy, the steel industry experienced a period of strong growth. During this period, steel production technology was improved, production processes were automated, and production scale increased. This leads to increased productivity, reduced production costs, and increased competitiveness in the steel industry. This is also considered a historical period that witnessed an increase in steel making.Steelmaking by BOF blast furnaceAt the beginning of the 20th century (1970s), many wars occurred. Leading to increased demand for steel to serve the needs of manufacturing and producing weapons and tanks. Western countries entered the stage of industrialization and modernization. Since then, the demand for steel has increased dramatically to serve the construction of infrastructure projects and buildings. From here, the appearance of "Oxygen Blowing Furnace (BOF)" and "Electrical Arc (EAF)" technology has created a major turning point for the development of the steel industry.Saturation phaseAfter going through a historical period that witnessed an increase in steelmaking, the steel industry entered a period of saturation (from the 1980s until now). During this period, the steel industry was able to balance supply and demand, and the growth rate gradually slowed down. Businesses in the industry are forced to expand their markets and seek new development opportunities to ensure continued growth and competition. However, the history of steel is still in the development stage, and we are aiming for more sustainable goals in the future.China currently dominates the global steel industryThe role of steel in today's lifeIt can be said that there is no field that does not use steel; steel is present almost everywhere. With the invention of steel and its durable and flexible properties, steel is known as an extremely important source of raw materials and is widely used in life, especially in the construction field. Below, let's learn about some of the roles of steel in today's life.The role of steel in constructionWith tough properties and the ability to be easily shaped at high temperatures. Steel invented has replaced iron, making it an indispensable material in the construction industry to increase the solidity and durability of projects. An important application of steel in construction is to use it to make reinforced concrete and house foundations, bringing stability to each project. In addition, steel is also used to build infrastructure, roads, public works, and transportation to serve the needs of the community. And until today's rapid development, there is still no material that can replace steel.The role of steel in everyday lifeBesides being an important element in construction, steel is also used in everyday life.

Carbon steel is steel made of iron and carbon with some other ingredients such as manganese, silicon, phosphorus,... Let's delve deeper into the characteristics, applications, and important aspects of this type of steel with AG真人游戏 Steel.Carbon steel is among the top 4 most popular types of steel, used in many fields such as industry, manufacturing, civil use,... because of its flexibility and hardness.The more carbon in the steel, the higher the hardness and durability of the steel, in which carbon steel components can contain up to 2.1 wt.% carbon. The relatively low production cost of carbon steel makes it more preferred over other types of steel. Below, AG真人游戏 Steel will explore with you the pros and corn, production methods and applications of carbon steel.Carbon steel is steel made of carbon along with other elementsWhat are the different types of carbon steel?Carbon steel is categorized into three types based on its carbon content:Low carbon steelLow carbon steel has a carbon ratio of 0.04 - 0.25% or 0.29% with small amounts of other elements. Therefore, steel has low hardness and durability, so it is also called mild steel. However, they exhibit good ductility and can be easily shaped by pressing or bending, even when cold-formed.Medium carbon steelMedium carbon steels with average carbon content (0.25 - 0.5%), providing good corrosion resistance and high durability. Medium carbon steel has good heat treatment and cutting performance but poor welding performance, requiring preheating in welding. This type of steel is mainly used in high-strength moving parts such as air compressors, pump pistons, turbine blades, gears, crankshafts, rollers,...High carbon steelThanks to the carbon content of 0.6 - 2%, high carbon steel has good bearing capacity and high durability. The hardness of this steel can be up to 60 - 65 HRC according to Rockwell C. High carbon steel is mainly used in the production of springs, wear parts and high-hardness tools.Each type of carbon steel exhibits unique properties and applicationsWhat is carbon steel made ofCarbon steel is primarily made up of iron and carbon, combined with a number of other ingredients such as manganese, silicon, phosphorus,... In which, the carbon content determines the mechanical properties and durability of the steel. If the amount of carbon is low, the plasticity is high, convenient for shaping, bending and vice versa. However, the hardness and brittleness of the product depends on the metallurgy and heat treatment process. The carbon ratio can range from 0.02 - 2.1% depending on the amount of steel but the common ratio is 0.1 - 0.3%.Pros and cons of carbon steelAdvantagesEach carbon steel type has unique mechanical properties when undergoing metallurgy and heat treatment. Manufacturers can adjust technical parameters to create outstanding advantages for carbon steels as follows:High durability and hardness: High carbon content enhances the steel's bearing capacity and resists environmental impacts.Corrosion resistance: Carbon steel has extremely good corrosion resistance, so it is often used in the chemical, petroleum and marine industries.Good bending and melting ability: The amount of carbon can be easily customized to help the steel have flexibility for shaping, which is crucial in manufacturing and construction processes.DisadvantagesCarbon steel still have some disadvantages such as:Easy to rust: Manufacturers often add about 10-12% chromium to the composition, which acts as a moisture-proof layer to help limit rust when exposed to the environment.Poor aesthetics: Carbon steel lacks the smooth, shiny surface like stainless steel. Therefore, they are often applied to products that do not require high aesthetics such as pipes, machinery, spare parts,...Carbon steel strength helps it be applied in many areas of lifeHow is carbon steel madeCarbon steel can be produced from iron ore, scrap steel or a combination of both without losing its properties and strength. By heating iron ore and coke in the absence of air at a temperature of about 1650 degrees Celsius, the molten iron is enriched in carbon from the burning coke. The remaining impurities combine with lime to form slag, which floats on the metal surface to be removed. The product initially contains approximately 4% carbon, which is then decarbonized to reduce it to the desired level. Decarbonization occurs by passing oxygen through the melt forming monoxide and carbon dioxide.Applications of carbon steelsPossessing many outstanding properties, carbon steel is a material widely used in many different industries, typically:Road and bridge construction: Carbon steel has good corrosion resistance and high durability, suitable for building infrastructure such as roads, bridges, buildings, tunnels,...Automobile industry: Carbon steel is an ideal material for car parts such as vehicle frames, wings, hoods, exhaust pipes,... because of its high hardness, lightness and durable structure that helps reduce weight and increase space efficiency for vehicles.Aerospace industry: With its lightweight properties and outstanding mechanical strength, carbon steel is used in the production of aircraft components, spacecraft bodies and rockets.Oil and gas industry: Carbon steels are used to produce equipment and oil pipes thanks to its good bearing capacity. This will ensure the safety and performance of pipeline systems under the harsh conditions of the oil and gas industry.Manufacturing and machinery industry: Carbon steel has ductility and flexible shaping, so it is suitable for processing and producing machine parts such as shafts, bearings, gears,...Carbon steel's resilience makes it ideal for infrastructure, vehicles, and machineryImport the best quality Vietnamese carbon steel at AG真人游戏 SteelAccording to Worldsteel, Vietnam ranked 12th in the world in crude steel output with 19 million tons in 2023 and belongs to the group of steel exporting countries with a turnover of over 10 billion USD.
