Hot Rolled vs Cold Rolled Steel: Overview and Differences

When 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.
