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

    price: contact company for price

    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.
