Cold Rolled Sheets

Cold Rolled (CR) Sheet Products involves cold reducing coils of hot-rolled, pickled product to a thinner thickness. The cold reduction operation induces very high strains (work hardening) into the sheet; thus, the sheet not only becomes thinner, but also becomes much harder, less ductile, and very difficult to form. However, after the cold-reduced product is annealed (heated to high temperatures), it becomes very soft and formable.

Cold rolled sheet products are used in a wide variety of end applications such as appliances – refrigerators, washers, dryers, and other small appliances, automobiles – exposed as well as unexposed parts, electric motors, and bathtubs. Cold rolled sheet products are used in these and many other areas of manufacturing. To meet the various end use requirements, cold-rolled sheet products are metallurgically designed to provide specific attributes such as high formability, deep drawability, high strength, high dent resistance, good magnetic properties, enamelability, and paintability.
