Hot rolling involves rolling the steel above its re-crystallization temperature (typically over 1700° F). At this temperature, it can be shaped and formed easily, and the steel can be made in much larger sizes.    Post the milling process at high temperature, the steel cools off and shrinks slightly thus giving less control on the size and shape of the finished product when compared to cold rolled.
