Because SPCE cold rolled steel commercial has not been annealed, its hardness is very high (HRB is greater than 90), and its machinability is extremely poor, so it can only perform simple directional bending less than 90 degrees (perpendicular to the coiling direction).
To put SPCE cold rolled steel commercial simply, cold rolling is processed and rolled on the basis of hot rolled coils. Generally speaking, SPCE cold rolled steel commercial is a process of hot rolling—pickling—cold rolling.
