As pickling, which uses strong acids to remove scale and other impurities. Cold Rolled Carbon Steel is then passed through rollers to reduce its thickness. Most cold rolling takes place in multiple passes and as the size of Cold Rolled Carbon Steel is further reduced, its strength and hardness both increase, but its ductility decreases. After cold rolling, heating the metal up in a process known as annealing can restore some of its ductility. The final Cold Rolled Carbon Steel may be manufactured in the form of sheets, strips, bars, or other forms.
