Abstract
A method is provided for further processing cold-rolled, stainless-steel sheet or strip by being induction-heated to an annealing temperature in the range of up to 2300 degrees Fahrenheit, causing the formation thereon of a scale of having thickness of less than 2000 Angstroms, followed by electrolytic descaling at high current density in an aqueous solution of 15 to 25 weight percent of sodium sulfate, maintained at a temperature of at least 150 degrees Fahrenheit.
