Distinction between hot rolled and cold rolled steel plate
1、The carbon content of hot-rolled steel plate is slightly higher than that of cold-rolled steel plate. The density is the same if the components are not very different.. Specific depends on the composition, hot rolled steel plate is just better ductility, steel is also subjected to pressure.
2、Hot rolled steel plate has low hardness, easy processing and good ductility.Cold rolled plate hardness is high, processing is relatively difficult, but not easy to deformation, high strength.
3、Hot rolled steel plate strength is relatively low, almost surface quality (low oxidation finish), but good plasticity, generally for medium and thick plate, cold rolled plate: high strength, high hardness, high surface finish, generally for sheet, can be used as a stamping plate.
