The chemical elements in steel alloys and their content can regulate the hardness, elasticity, ductility, oxidation resistance and strength of steel.Because of this diversity, we currently have more than 3,000 different types of steel. So how do these steel types differ in terms of grade, properties and structure? In this article, AG真人游戏 Steel will introduce you to the 4 most common steel along with essential information about each type.Understanding the various types of hardened steel is crucial for selecting the right material for your applicationHow many types of steel are there?Steel is classified according to its composition, depending on the carbon content and elements. We have 4 steel types including:Carbon steelCarbon steel has two main components: iron and carbon, other elements account for an insignificant proportion. Despite having only two elements, steel variety is used for different applications by adjusting the carbon content.Low carbon steel: carbon content less than 0.25%, high ductility, specialized for making wires, bolts, pipesMedium carbon steel: 0.25-0.6% carbon content helps the steel have high strength and lower ductility than low carbon steel, used to make gears and rails.High carbon steel: carbon content 0.6-2% and often used to make nails and sharp tools. Stainless steelStainless steel is well known in the field of manufacturing medical equipment and instruments, but in fact its application range is much larger. They are iron alloys containing a minimum of 10.5% chromium, which imparts a bright finish and excellent corrosion resistance. Not only has its aesthetic value, chromium is also known for its extremely good oxidation resistance and high durability. Therefore, stainless steel is very popular, widely used in the field of household appliances, furniture,...There are 4 main stainless steel types, including:Austenic: High chromium and nickel content enhances corrosion resistance, good durability, easy to clean, used to produce kitchen equipmentFerritic: Economical due to low carbon and nickel content, known for its aesthetic appeal and bright finish, commonly used in the automotive industry.Austenitic - Ferritic (Duplex): The combination of austenitic and ferritic alloy increases the carbon content, providing twice the strength, ductility and corrosion resistanceMartensitic: Martensitic alloy undergoes rapid cooling so it has good plasticity and heat resistance, often used for making medical tools, scissors,...Stainless steel is renowned for its corrosion resistance and durability in various industrial applicationsAlloy steelAlloy steel combines many different elements with concentrations ranging from 1-50% to change the mechanical properties of the product. Depending on the proportion of alloying elements, we have 3 main types of steel including:Low alloy steel: total content of other metallic elements is less than 2.5%Medium alloy steel: total content of other metal elements 2.5-10%High alloy steel: total content of other metal elements is over 10%.In the fields of construction and household appliances, low alloy steel is preferred for its strength, thanks to the presence of elements like manganese, chromium, silicon, nickel, and more, all of which are under 10%.Alloy steel: Mixed elements for varied propertiesTool steelTool steel has high carbon content (0.7 - 1.4%) and low S and P impurities (< 0.025%). Going through the process of tempering at high temperatures and cooling quickly, repeatedly, helps tool steel be durable and heat resistant. They are often used in the fields of tool and machinery manufacturing.Depending on the final product, the source of tool steel materials is also different:Air - hardening: Increasing the chromium content in the composition helps steel to be exposed to high temperatures without deformation.Water - hardening: Steel is continuously cooled during the production process, used to make common tools.Oil - hardening: Tool steel is protected by a layer of oil against wear resistance, often used for knives and shears. Hot - working: This is a type of steel that can withstand extreme heat and is often used in forging or casting.Shock - resisting: Ingredients include small amounts of carbon, silicon, and molybdenum to increase the hardness of steel, suitable for hole punches and chisels.Learn about steel classificationsIn addition to the 4 common types of steel mentioned above, more than 3,000 remaining types of steel can be classified based on the following criteria:Composition: Content of steel, iron, carbon and some other chemical elements (Si, Mn, P, S, Cr, Ni,...).Treatment method: pickling and oiling method, hot rolling, cold rolling, hot-dip galvanizing,...Production method: Electric furnace, continuous cast,...Microstructure: Austenitic, ferritic, martensitic,...Physical strength: ASTM, JIS, BS,... standardsDe-oxidation process: killed or semi-killed,...Heat treatment: annealed, tempered,...What are different grades of steelSteel grade is a term used to denote the bearing capacity of steel. There are many different steel symbols associated with the "Production Standards Applied" of that steel. Currently, two typical steel grade classification systems include:ASTM: Alphanumeric classification represents the overall classification and specific properties of steel, such as ASTM A123, ASTM A53/A53 - 18,...SAE: Classification with 4 digits indicating steel types, alloying element content (first two digits) and carbon content (last two digits).Address to import genuine steel at good prices in VietnamAccording to WorldSteel's report, Vietnam shipped 19 million tons of crude steel in 2023, ranking 12th worldwide.

In this article, AG真人游戏 Steel will help you classify the most common hollow sections along with their detailed internal characteristics and structures.1. What are Hollow sections?Hollow sections are one of the metal structures made from cold rolled steel and formed into hollow tubes. The feature of hollow sections is that there is an open edge extending over the entire steel bar with many different shapes such as round, square, rectangular and a variety of sizes according to ASTM A500, A1085 and A1065,鈥here are 4 types of hollow sections with flexible structure, properties and applications for each use:1.1. Square Hollow SectionSquare Hollow Section (SHS) is a common form of steel pipe, considered a combination of RHS and CHS. SHS products have a flat surface, easy to join and weld, equal and symmetrical sides, width from 2-30mm, length from 6-12mm. SHS is appreciated for its durability, aesthetic value, strength, meets EN, ASTM, GB, Jis standards and the requirements in construction.1.2. Rectangular Hollow SectionThe Rectangular Hollow Section (RHS) has a flat surface so it is flexible in joining, welding and assembling as required. RHS products have a rectangular shape so it is easy to join with other members without edge preparation. This is a reasonable choice in terms of structure and cost-effective for many projects.1.3. Circular Hollow SectionOne of the most typical hollow sections is the circular hollow section (CHS) used in construction, mechanical and structural projects. They have a smooth surface, no sharp or protruding edges, so they have high aesthetic value. Similar to SHS and RHS, CHS products are durable, strong, easy to shape, suitable to be used as materials for projects requiring low temperature.1.4. Seamless Hollow SectionSeamless Hollow Section is a long steel form with a seamless hollow section, with no joints or welds between the four faces of the mold. They are made by a hot manufacturing process, in which the raw material is steel billets that are heated at high temperatures to be easily bent and shaped. Seamless Hollow Section is used as a pipeline system to transport liquids, support hydraulics, and mechanical structures. The advantages of Seamless compared to other types of hollow section are high strength, no cracking, compressive capacity of very stable mechanical properties.2. Benefits of using hollow sectionsFlexibilityHollow sections have smooth, flat surfaces along the edges, so they are easy to assemble and connect with other products to create the necessary materials for the project. Before welding to another flat surface, the hollow sections cut should be straight and clean. Hollow sections products are very resistant to heat, pressure and environmental impacts, so they have a long life expectancy.Various sizesHollow sections have many different sizes and shapes, so customers have the most suitable choices for their projects. The manufacturer can completely fabricate, assemble or change the specifications of these metal components to the requirements of the buyer.

Pipes and tubes are present in many applications in automotive, aerospace, agriculture, architecture,... The use of aluminum or stainless steel pipes and tubes will need to be justified on the characteristics and requirements of the project. To help you choose the best option, here are some differences between stainless steel and aluminum pipes and tubes.1. Top 5 differences Aluminum and Stainless Steel Pipes and Tubes1.1. StrengthAluminum and Stainless steel pipes and tubes are high-strength materials with good bearing capacity. However, compared to weight, aluminum is lighter than steel, so it is suitable for nature projects both strength and lightness are needed. Meanwhile, stainless steel is an alloy with high carbon, chromium and molybdenum components, making steel harder, more resistant to impact, stress and pressure than aluminum. These outstanding properties make stainless steel tubular products one of the most durable industrial materials.1.2. WeightCompared to weight, steel is 2.5 times heavier than aluminum, so for applications that need lightness such as household appliances (kitchen utensils, medical instruments) or aerospace, aluminum pipes and tubes are more preferred. In contrast, for projects that do not require weight, stainless steel will be used to save costs1.3. CostAluminum and stainless steel pipe and tube prices flux based on market fluctuations and input fuel costs. The commercial quality of aluminum and stainless steel are similar in price per kilogram, but in terms of cost, aluminum is typically more cost-effective then stainless steel. 1.4. Corrosion resistanceBoth materials have corrosion resistant properties, but stainless steel pipes and tubes have an edge thanks to the structure with more chromium and molybdenum components - effective protective and against corrosion coatings.The thin layer of aluminum oxide protects aluminum pipes and tubes from rust but cannot avoid corrosion under the effects of the environment (weather, climate, humidity,...).1.5. ConductivityCompared to other metals, stainless steel is a poor conductor, while aluminum is known for its good thermal and electrical conductivity. That is why electronic components in cars, air conditioners, high voltage power lines or heat conduction applications (kitchen suction pipes, boiler systems, ...) are made from aluminum.2. Applications of aluminum and stainless steel pipes and tubes2.1. ConstructionThe strength of stainless steel pipes and tubes to be used as a material for the bones of high-rise buildings, stadiums, roads, stairs and other projects requiring high durability.The majority of skyscrapers in the world are made from aluminum because of its lightness and strength-to-weight-ratio making it the ideal material, sturdy and time-saving in construction.2.2. EnergySteel frameworks are key for nuclear power, natural gas, solar energy projects,... Stainless steel pipes and tubes are also used as transformer cores, electromagnetic shields and construction details of cranes and forklifts.Aluminum's low density and high thermal conductivity are suitable for power transmission lines. It is an excellent alternative to copper as it has both better electrical and thermal conductivity, low cost and ease of maintenance.2.3. TransportationIn addition to being the main material in the automobile manufacturing industry, stainless steel pipes and tubes are also used to manufacture rails, jet engine components, boats and other high-strength transportation requirements.Meanwhile, the aerospace industry's need to increase fuel efficiency has made aluminum the critical metal in constructing planes, spacecraft and many other modern vehicles.2.4. Packing and consumer goodsMore than half of the weight of household appliances such as refrigerators, ovens, washing machines, air conditioners,...comes from stainless steel. Steel pipes and tubes are also commonly used in metal stairs and small details such as screws, nails,...Aluminum products are coated with a durable aluminum oxide layer, preventing the aluminum inside from melting and making it safe for consumers' health. Thanks to this advantage, it is widely used in making kitchenware and food packaging and an essential material in electronic devices such as phones, televisions, computers, and LED bulbs,...Distinguishing the critical differences between aluminum and stainless steel pipes and tubes will help you easily choose the suitable material for the nature of the project.
