  • Cold Rolled SteelMetal Supermarkets

    Sep 11 2014 · Hot Rolled Steel. Hot rolling is a mill process which involves rolling the steel at a high temperature (typically at a temperature over 1700° F) which is above the steel s recrystallization temperature. When steel is above the recrystallization temperature it can be shaped and formed easily and the steel can be made in much larger sizes.
