WebHow does cold rolling steel make it stronger and harder? Increased Strength Cold-rolled steel is significantly stronger than hot-rolled steel. As the rollers compress the steel at room temperature, the steel becomes stronger due to strain hardening. Although there are exceptions, cold-rolled steel is typically about 20\% stronger than its hot ... Web4.3.2 Cold rolling. Whenever appropriate, cold rolling (Figure 22) follows the hot rolling process step. Temperature ranges typically from 60°C to 180°C and the desired reduction …
