Cold rolling is a process where steel is passed through a series of rollers at ambient temperatures, usually below its recrystallization point. This technique is typically used after hot rolling to improve the mechanical and surface properties of steel products. The cold rolling process not only reduces the thickness of the steel but also enhances its strength through strain hardening.
