ABSTRACT:
A process for treating a stainless steel strip in an electrolytic tank produces a stainless steel with improved surface properties. The process subjects the stainless steel to a bright annealing process, followed by an electro-chemical treatment stage at current densities of up to 200 A/dm2. The electro-chemical treatment is typically in a sulfate containing electrolyte solution. The current density can range from about 20 A/dm2to about 200 A/dm2.
