Low Carbon Cold Rolled Steel Strips

The cold rolled strip is a steel product that is produced from a hot rolled strip that has been pickled. The coil is then reduced by a single stand cold roll steel mill straight away or reversing mill or in a tandem mill consisting of several single stands in a series. The strip is reduced to approximately final thickness by cold-rolling directly, or with the inclusion of an annealing operation at some intermediate thickness to facilitate further cold reduction or to obtain mechanical properties desired in the finished product. The coil is then slit to the desired width through the process of roll slitting.

The cold rolled steel strip is used in body panels and automotive components, tubes, appliances such as refrigerators, washers and dryers, building materials as well as electrical components.
