What are the differences between hot-rolled and cold-rolled plates?

The carbon content of hot-rolled steel plate can be slightly higher than that of cold-rolled steel plate. Hot-rolled steel plate has low hardness, easy processing and good ductility. Cold-rolled plate has high hardness and is relatively difficult to process, but it is not easy to deform and has high strength. Hot-rolled steel plate has relatively low strength and poor surface quality (low oxidation finish), but good plasticity. It is generally medium and thick plate, cold-rolled plate, high strength, high hardness, high surface finish, generally Pu plate, which can be used as stamping plate. The production process of hot-rolled steel plate and cold-rolled steel plate is different.
Hot-rolled steel plate is rolled at high temperature, and cold-rolled is rolled at room temperature. Generally speaking, cold-rolled steel plate has better strength and hot-rolled steel plate has better ductility.
The general thickness of cold-rolled steel plate is relatively small, and hot-rolled steel plate can have a larger thickness. The surface quality, appearance and dimensional accuracy of cold-rolled steel plate are better than those of hot-rolled steel plate, and its product thickness can be rolled as thin as about 0.18mm, so it is more popular. For the acceptance of products, professionals can be invited to do it. Although both are main materials commonly used in the storage shelf industry, there are huge differences between them.
