Hot rolled steel is after high temperature heating rolled steel, its strength is not very high, but enough to meet our use, its plasticity, weldability is good, so we are more commonly used; Cold rolled steel is common hot rolled steel after strong drawing beyond the strain hardening stage of steel, it has high strength, but poor toughness, weldability, relatively hard and brittle. Hot rolling is processed at high temperature. Hot rolling means that the material needs to be heated during or before steel rolling. Generally, rolling should be heated to the recrystallization temperature above.
