  • Cold Rollingprocess overviewEngineeringClicks

     · 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.
