Cold-rolled SPCD mechanical generally steel is processed from hot-rolled sheets at room temperature. Although the temperature of the steel sheet will be heated during the processing, Cold-rolled SPCD mechanical generally steel is still called cold-rolled. Due to the continuous cold deformation of hot rolling, the mechanical properties are relatively poor and the hardness is too high.

Cold-rolled SPCD mechanical generally steel must be annealed to restore its mechanical properties, and those without annealing are called hard rolled coils.
Cold-rolled SPCD mechanical generally steel have widely application such as automotive manufacturing, electrical appliances, vehicles, aerospace, precision instrument and food processing.
