While cold hardening promotes greater strength and hardness, as well as lower plasticity and viscosity, these properties may differ along the cross section of the coil. Therefore, once discharged from the rolling mill, most merchant cold-rolled coils go through heat treatment, ie annealing, in bell-type furnaces or on continuous lines.
