Annealing of stainless steel after cold rolling is to eliminate work hardening through the process of recrystallization to achieve the purpose of softening; the purpose of pickling is to remove the oxide layer formed on the surface of the steel strip during the
annealing process,and the second is to passivate the surface of the stainless steel . Improve the corrosion resistance of steel plate.
