Steel sheets are very widely used profiles used directly or used in the production of other profiles. Steel sheets are defined under certain standards, common standards in Iran are usually German, then American ASTM standard and standard Russian excavation are rarely used.

Is First rate sheet steel in high demand?
Heating processes are used more than cooling, as they require less power and energy. Hot rolling occurs at temperatures above the recrystallization of materials, while in steels it is above 1000 ° C. First, the ingots or slabs are heated above the above temperature, in the next step they enter the rolling machine and continuously roll the desired final shape (sheet or profile). Because the metal is easier to deform at high temperatures, it can be produced in larger quantities than cold rolled steel, which keeps the market price of hot rolled steel low.
Steel cools to room temperature, known as normalization, a process that changes the microstructure of the material to increase ductility and toughness. Ductility is particularly important when creating materials (eg sheet metal bending) to provide the required shape. Hot rolled steel is subjected to internal stresses due to subsequent cooling, and the results of non-uniform measurements have a tolerance of 2 to 5%. It also has a crusty surface due to oxidation, making it not the highest surface quality. Hot rolled products can be easily identified by touching the surface. The surface of the hot rolled sheet is rough and lacks oily film. Rolled steels are a good option when precise tolerances are not taken into account, they even have the advantage of accurately measuring the price.
Some common uses of hot rolled steel include construction, pipes and tubes, truck chassis, doors and racks, railway tracks, and auto parts. Unlike hot rolling, cold rolling of metal takes place below its recrystallization temperature. The whole process starts like hot rolling to get its original shape without too much resistance. The metal is then cooled to room temperature. The semi-finished products are then fed into the reduction cylinder. The metal is rolled to a thickness of 0.5 to 3 mm in the case of low carbon steel and 0.5 to 5 mm in the case of stainless steel.
This material is cooled using oil, which also acts as a lubricant during the rolling process. As the sheet between the rolls gets thinner, its speed increases. If there is no oil film to reduce contact, wear and deformation will occur in the material. Hence, cold rolled steel with an oily and smooth surface can be identified. Hardening occurs because the work is done at temperatures below the recrystallization temperature. The rollers deform the plastic. Therefore, cold rolled steel has higher yield strength than hot rolled steel. For example, a hot rolled steel product can have a yield strength of 235 MPa. By comparison, a cold rolled steel product of the same chemical composition has a yield strength of 365 MPa. For more information about steel sheet price, visit our site.
