What Is Cold Working or Work Hardening? - .

Cold rolling is the most common method of work hardening. This involves the metal being passed through pairs of rollers to reduce its thickness or to make the thickness uniform. As it moves through the rollers and is compressed, the metal grains are deformed. Examples of cold-rolled products include steel sheets, strips, bars, and rods.
