Cold rolling is typically performed on a steel sheet or coil that has already been processed through hot rolling. The primary objective of cold rolling is to improve surface finish, increase tensile strength, and enhance overall yield strength. The procedure involves passing the steel material through a pair of rollers at ambient temperatures, which compresses and elongates the metal. The reduced thickness can range from a fraction of a millimeter to several millimeters, depending on the desired product specifications.
