contactWhen comparing hot rolled vs cold rolled steel, one of the major points to consider is the recrystallization point. Cold rolling occurs when the metal material is able to form “new grains.” The rolling and bending of the metal often destroy old grains. Cold work on steel may reduce its strength, so manufacturers add a final step of annealing.
contactHot rolling mills typically produce sections of steel at various dimensions from billets of steel. The manufactoring process involves passing bars of steel at high temperatures. This happens through rotating rolls to reduce the thickness and shape the sections. It furthers proceeds into cooling and cutting to length or coiling into rolls for ...
