Abstract
PURPOSE: To provide the subject method of processing the surface of a stainless steel to give the same a compression residual stress to eliminate the oxidized membrane therefrom, whereby generation of microcracks is prevented and the processed article of high reliability is obtained.
CONSTITUTION: As a method of eliminating the oxidized membrane of molding processed articles using stainless steel, sand blasting using sands of more than 200 meshes without carrying out pickling or honing to eliminate the oxidized membrane. By this procedure, generation of etch pits is prevented, and there is no possibility of generation of microcraks from the grain boundary. The tension residual stress on the surface of the processed articls can be rendered into a compression residual stress, and there is removed a possibility of the microcracks on the surface of the processed article being age opened
