Commercial Quality Excellent Mechanical Property Coil Type CRC Cold Rolled Steel







Basics



Brief Introduction


Coil Type CRC Cold Rolled Steel is steel that has been worked below its recrystallization temperature by passing it between a pair of rollers. Recrystallization temperature is the temperature at which grains in the lattice structure of the metal have been rearranged, leaving it free of strain and deformations. Coil Type CRC Cold Rolled Steel is pre-treated before being cold rolled with a process known as pickling, which uses strong acids to remove scale and other impurities. Coil Type CRC Cold Rolled Steel is then passed through rollers to reduce its thickness. Most cold rolling takes place in multiple passes and as the size of the Coil Type CRC Cold Rolled 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 Coil Type CRC Cold Rolled Steel may be manufactured in the form of sheets, strips, bars, or other forms.
