What is the difference between hot rolled steel and cold rolled steel?

The carbon content of hot-rolled steel sheet is higher than that of cold-rolled steel sheet. Hot rolled steel sheet has low hardness, easy processing and good ductility. Cold-rolled sheet has high hardness and is relatively difficult to process, but it is not easy to deform and has high strength.

The production process of hot-rolled steel plate and cold-rolled steel plate is different, hot-rolled steel is rolled at high temperature, while cold-rolled steel is rolled at room temperature. The general thickness of cold rolling is relatively small, and the hot rolling can be larger.
