What is the difference between cold-rolled steel sheet and cold rolled roll?
May 25, 2017

Cold rolled coil is a cold rolled steel plate, usually called rolling hard roll, because of continuous cold deformation caused by cold hardening of the rolling hard roll strength, hardness rise, toughness and plastic index decline, so stamping performance will deteriorate, can only be used for simple deformation of the parts.

Cold Rolled steel plate is processed by hot-rolled plate at room temperature, although in the process of processing because the rolling will also make the steel plate heating, even if it is called cold-rolled. Because of hot rolling through continuous cold deformation of cold-rolled, in mechanical performance is relatively poor, hardness is too high. It is necessary to undergo annealing to restore its mechanical properties without annealing, called rolling hard rolls. Rolled hard rolls are generally used to make products without bending and stretching.
