What Is Cold Working or Work Hardening? ThoughtCo

Nov 13, 2019· 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 coldrolled products include steel sheets, strips, bars, and rods.
