The Differences Between Hot and Cold Rolled Steel

COLDROLLED STEEL. As you might suspect, the manufacturing process behind coldrolled steel is a bit different. Despite the name, this process refers to steel that is pressed with the pressure of a roller at room temperature. Compared to hotrolled steel, coldrolled steel has a nearly 20% increase in strength through the use of strain hardening.
