What's the difference between cold rolled strip and cold rolled strip?
Cold rolled steel sheets are made from hot rolled sheets at normal temperatures. Although they are rolled during processing, they can also cause steel plates to heat up. Nevertheless, it is called cold rolling. Because of the cold rolling of continuous hot rolling, the mechanical properties are poor and the hardness is too high. It must be annealed to restore its mechanical properties. Rolled rolls are generally used to make products without bending or stretching.
Cold roll is usually called hard roll, due to continuous deformation caused by cold hardening the volume rolling hard strength, hardness, toughness index rise decline, so the stamping performance will deteriorate, only for a simple deformation of parts.
The term "steel coil" is strip steel, whose width is less than 600mm. It is called "narrow band", so cold rolled coil is called cold-rolled strip
