Cold Rolling – Process Overview Matmatch

Cold rolling takes the hot rolled product and processes it further After hot rolling the steel is cooled to room temperature then passed through cold rollers at a temperature lower than its recrystallisation temperature This rolling process is called annealing and relieves stress and leads to a higher yield strength and greater hardness This is due to reorientation of the grain
