Annealing of Cold Rolled SteelIspatGuru
To recover the ductility cold rolled steels need to undergo an annealing process for the relieving of the stresses that have buildup within the microstructure during the process of cold rolling Annealing consists of heating of the steel to above the recrystallization temperature soaking at that temperature and then cooling it.
