Q:What is hard cold rolled coil? And what are its characteristics?

Hard cold rolled coil is a kind of cold rolled, and cold rolled coil, cold plate, cold rolled strip is equivalent to belong to the cold rolled products. It is made of hot rolled steel coil as raw material, after pickling to remove oxidation skin for cold rolling. Due to the absence of annealing treatment, the strength and hardness of the hard cold rolled coi increases, but the toughness index decreases, so the stamping performance decreases, and can only be used for simple deformation of the parts.
