The surface finish of CR pipes and sections is better than the HR pipes and sections. Rolling of steel is done at varying degrees of temperatures, if rolling is done at or below room temperature, it is considered cold rolled. Cold rolling (Cr pipes) has the added effect of hardening and strengthening the material. It also improves the surface finish and holds tighter tolerances.
