Product Description

Hot rolled plate strength is relatively low, almost surface quality (low oxidation finish), but good plasticity, generally for thick plate, cold rolled plate: high strength, high hardness, high surface finish, generally for sheet, can be used as a stamping plate.

Hot rolled steel plate, mechanical properties are far less than cold processing, is inferior to forging processing, but has better toughness and ductility

Cold-rolled steel plate has a certain degree of work hardening, low toughness, but can reach a good strength ratio, used for cold bending spring and other parts, and because the yield point is close to the tensile strength,
