Rolling metalworking Wikipedia

Cold rolling occurs with the metal below its recrystallization temperature usually at room temperature, which increases the strength via strain hardening up to 20%. It also improves the surface finish and holds tighter tolerances.Commonly coldrolled products include sheets, strips, bars, and rods; these products are usually smaller than the same products that are hot rolled.
