The method of processing cold-rolled stainless steel strip or plate, the method comprising the steps of:

To clean the stainless steel surface with a solution selected from the group of water and aqueous solution of alkaline and acid-based compound in a sufficient amount to make the subsequent annealing process, reducing scale formation and the formation of scale thickness more uniform ;
Along the width direction of the steel uniformly transverse flux electromagnetic induction heating annealing, the heating temperature up to 2300 degrees Fahrenheit, so that the steel surface to generate a relatively uniform thickness of about 1200 Angstroms or less scale;

The stainless steel bath in an electrolyte to its electrolysis treatment to remove the oxide layer, the electrolyte is at least one selected from the group including alkali metal or ammonium hydrochloric acid, sulfuric acid and nitrates an aqueous solution of a neutral salt by water, the solution was maintained at a temperature above 150 degrees Fahrenheit, electrolysis current density per square inch is about 0.1 to 1.0 amperes of low current density, so that the oxide layer is completely removed after wash and wet wipe.
