The roller does not only decrease the thickness of the sheets but also refines the grain structure and hardens the steels. complete SPCC material steel add more good dimensional properties than SPHC Steels. Also, after the cold rolling process there are some additive processes like rewinding, annealing, and then skin passing to make a complete SPCC material steel with bright finish.

Complete SPCC material steel indicates that a cold-rolled carbon sheet is generally used, which is equivalent to China’s Q195-Q215A. No stamping test is required. The tensile test must be ensured. Add T after the grade to indicate SPCC-T or SPCCT.
