Erw Steel Pipe Used Jis G3141 Spcc Sd Cold Rolled Coil With No Pinholes - China

Cold Rolled Steel Coil 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.

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.

The 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 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 Cold Rolled Steel Coil may be manufactured in the

form of sheets, strips, bars, or other forms.
