Abstract
A method for producing bright surface quality stainless steel strip by continuous annealing cold-rolled strip in air followed by electrolytically descaling said annealed strip by making the strip the anode and applying electric current to the strip while the strip is in an electrolyte consisting essentially of an aqueous solution of at least one neutral salt which may be a chloride, sulfate or nitrate or an alkali metal, including aluminum, with the pH of the electrolyte being maintained between 1 and 7. In this manner, a scale-free, bright annealed-like surface is produced after air annealing without requiring annealing in a controlled atmosphere furnace.
