Cold rolled sheet is further rolled from hot rolled steel. It is widely used in auto parts and electrical appliance manufacturer. Due to rolling without extra heating, the cold rolled steel is clean on surface, bright and high accuracy.
The thickness accuracy of cold rolled products is determined by the cold rolling process. Rolling force and strip tension are computer-controlled to minimize thickness deviations during rolling, based on measurements of the strip thickness at the entry and delivery sides of the mill.

904L super austenitic stainless steel is a kind of low carbon, high nickel and molybdenum austenitic stainless steel with rust resistance and acid resistance.
