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.

A temper mill is also used to make cold rolled after annealing to assure a consistent quality. After the material is made hot rolled, it needs to be pickled and cold reduced. Cold reducing increases the yield strength and the material can be too hard to be used for any type of deep draw work or accurate bending.
