What is hot rolled sheet? What is the difference between it and cold rolled sheet?

2023-09-11

The carbon content of hot rolled steel plate can be slightly higher than cold rolled steel plate. Hot rolled steel plate hardness is low, easy to process, good ductility. Cold rolled steel hardness, processing is relatively difficult, but not easy to deformation, high strength. Hot rolled steel plate strength is relatively low, the surface quality is almost (oxidation \ low finish), but good plasticity, generally for the thick plate, cold rolled plate, high strength, high hardness, high surface finish, generally for the sheet, can be used as a stamping plate. Hot rolled steel plate and cold rolled steel plate production process is different. Hot rolled steel plate is rolled at high temperature, cold rolled is rolled at room temperature. Generally speaking, cold rolled steel plate has better strength and hot rolled steel plate has better ductility. Cold rolled is generally smaller in thickness, and hot rolled can have a larger thickness. The surface quality, appearance and dimensional accuracy of cold rolled steel plate are better than that of hot rolled plate, and the thickness of the product can be rolled as thin as 0.18mm or so, so it is more popular. For product acceptance, you can ask the professionals. Both are commonly used in the storage racking industry, but there are huge differences between the two main materials.
