Cold rolled sheet, or CRC, is the flat product of the cold rolling mill, starting from hot rolled strip coil after being pickled and oiled. Cold rolling increases the dislocation density of the steel’s internal structure, which increases the strength of the steel but also increases its brittleness. Many cold rolled processes are followed by an annealing process to “temper” the steel’s structure and to relieve the stress imposed on the steel from the cold rolling mill.
