Product Description

  Prime Quality Grade SPCC ST12 DC01 Q195 Steel Material Cold Rolled Steel Coil from Shanghai Manufacturer
  Brief Introduction Steel Material Cold Rolled Steel Coil 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. Steel Material Cold Rolled Steel Coil is pre-treated before being cold rolled with a process known as pickling, which uses strong acids to remove scale and other impurities. Steel Material Cold Rolled Steel Coil is then passed through rollers to reduce its thickness. Most cold rolling takes place in multiple passes and as the size of the Steel Material Cold Rolled Steel Coil 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 Steel Material Cold Rolled Steel Coil may be manufactured in the form of sheets, strips, bars, or other forms.   Production Flow Chart   Specification 1. Thickness: 0.4-2.0mm 2.
