PURPOSE:To prevent the resticking of oxide scale and to increase descaling capacity by electrolytically treating a cold rolled stainless steel strip as the cathode in an aq. neutral salt soln. at a prescribed current density regulated according to the concn. of the neutral salt soln. CONSTITUTION:A cold rolled stainless steel strip annealed in an oxidizing atmosphere is electrolytically treated as the cathode in an aq. neutral salt soln. At this time, the cathode current density (x) is regulated to >=10+0.8A/dm<2> in case where the total concn. (c) of Fe, Cr and Ni ions in the neutral salt soln. is >=2.5g/l and to x>=12A/dm<2> in case where the total concn. (c) is <2.5g/l. The electrolytically treated steel strip is pickled.
