WEBIn simple terms, cold rolling is the process of strengthening steel by changing its shape without using heat. Cold rolling, unlike hot rolling such as with hot rolled steel, can only occur when a metal is below its recrystallization temperature. Where hot rolling is performed using high temperatures, cold rolling is performed at room temperature.
