摘要：
A method for hardening the surfaces of work pieces made from stainless steel includes submerging the work pieces into a molten salt bath having the composition: potassium acetate 60-100 weight %; sodium acetate 0-100 weight %; metal salt 0-2 weight %, and are subjecting the work pieces to the molten salt bath for a period of 24 to 240 hours, during which the temperature of the molten salt bath is maintained less than 400° C.
