  • The Differences Between Hot and Cold Rolled

    HOT-ROLLED STEEL. Hot-rolling refers to a mill process in which you roll the steel at a temperature above its recrystallization temperature; a heat that typically exceeds 1000° F. When steel is heated past its recrystallization point, it becomes more malleable and can be properly formed and shaped. It also allows for the ability to produce larger quantities of steel. The steel
