Extensive deformation given to the steel at room temperature during the cold rolling process signifi-cantly reduces the ductility and formability of cold rolled sheets. This necessitates annealing, where the cold rolled sheets get stress relieved through the mechanisms of recovery, recrystallization and grain growth.
