Hot rolled and cold rolled steel are both important raw materials in the production of many types of finished steel products. So what are hot rolled vs cold rolled steel? What is the difference between these two types of rolled steel and what are the applications of these two types of rolled steel?Let's explore more deeply with AG真人游戏 Steel about the basic knowledge of hot rolled & cold rolled steel as well as the benefits it brings to businesses in many different fields through the article content below.Let's learn more about hot rolled steel and cold rolled steelLearn about hot rolled and cold rolled steelHot rolled and cold rolled steel are important raw materials in the steel production process. Both types of steel are metals whose production requires high technical skills and solid expertise. Next, let's learn about hot rolled steel vs cold rolled steel.What is hot rolled steel?Hot rolled steel is a type of steel produced through a hot rolling process at high temperatures, often exceeding 1000掳C. This process can change the material and shape of the metal. Hot rolled steel products are often dark green, less shiny and lack aesthetics.Hot rolled steel are usually produced at high temperaturesWhat is cold rolled steel?Cold rolled steel is essentially a hot rolled steel that has been cooled and re-rolled at room temperature. After going through the process of gradually reducing the length of the cold rolled steel, it has appropriate dimensions and smooth surface quality. Because it goes through many processing processes, cold rolled steel often has a higher price than hot rolled steel, so product quality as well as aesthetics are also highly appreciated compared to hot rolled steel.Cold rolled steel has a smoother surface than hot rolled steelDifference between Hot-rolled and Cold-rolled steelTo distinguish between hot rolled and cold rolled steel, in addition to learning about the nature through the definition of each type of steel coil mentioned above, we need to differentiate through factors such as the normal thickness, price of each type, surface, and edge of the steel coil. In addition, we can consider additional factors such as tolerance, accuracy, and storage method of each type of steel coil. Let's see the differences between these two types of rolled steel through the table below.Table comparing the differences between hot rolled steel and cold rolled steelComparison criteriaHot-rolled steelCold-rolled steel Thickness>0,9 mm0,15mm - 2,0mmSurface, colorThe surface is rough, the blue-gray color turns rusty red after a long timeSmooth surface, light gray colorEdgeThe two edges of the roll are often rounded, rough, and turn rusty when left for a long timeUsually neatly trimmedTolerance The tolerance is larger due to the production process; the hot temperature cools down, so the steel deforms itself and cannot be controlledTolerances are tighter due to reduced temperatures throughout the process and strict control of the coolant actionPrice Cheaper than cold rolled steelHigher than hot rolled steelPreservationHot-rolled steel coils can be left outdoors for long periods of time without using coveringsShould be stored indoors and should be covered with a cover to prevent scratches on the steel surface.Advantages and disadvantages of hot rolled and cold rolled steelEach type of steel will have its own advantages and disadvantages. Let's learn about the advantages and disadvantages of hot rolled and cold rolled steel through the table below.Advantages and disadvantages of hot rolled steel and cold rolled steelCriteriaHot-rolled steelCold-rolled steel AdvantagesEasy to bend, easy to shapeSo Easy To PreserveGood bearing capacityLower price than cold rolled steelThe quality of the finished product is consistentThe surface is highly aestheticHigh durability and hardnessHigh accuracyDisadvantagesLow aestheticsDifficult to control size and shapeEasy to rustThe price is higher than hot rolled steelApplications of hot rolled and cold rolled steelHot-rolled and cold-rolled steel are two dominant types of steel on the market today. In addition to being commonly used in steel production, hot rolled vs. cold rolled steel are also indispensable materials for the production of many popular civil products today.Hot rolled steel is an indispensable raw material source in the steel production process. In addition to being a source of raw materials for the production of cold rolled steel, hot rolled steel is also used to serve the construction, mechanical, transportation, household appliances, and other industries that use billets, beams, and H-shaped steel.Cold rolled steel is mainly used to produce products such as steel sheets and galvanized steel coils with square and round details and smooth surfaces. Cold rolled steel has high aesthetics and precision, so they are often used in technical and aesthetic projects such as manufacturing cars, air conditioners, refrigerators, food containers, televisions,...Galvanized steel pipe is one of the applications of hot rolled steelWhere should you buy hot rolled steel and cold rolled steel?Hot rolled and cold rolled steel are used in many fields. Therefore, businesses should choose products with good quality and according to standards to ensure quality.
