Abstract (en)
[origin: CA2642322A1] 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.degree. C.
