What Is Cold Rolled Steel?

Cold Rolled Steel

Cold rolled steel is processed at low temperatures, below its recrystallization temperature, which allows it to be shaped and sized with greater precision compared to hot rolled steel. In the process, the steel is passed through a set of rollers to reduce its thickness, hardening the steel, and improving the uniformity of the surface. Cold rolled steel typically has a finer surface finish and tighter tolerances making it ideal in automotive parts, appliances, and construction materials. However, it is more brittle than hot rolled steel due to the rolling stress which may require additional processing steps, such as annealing, to relieve internal stresses.
