摘要： Disclosed are stainless steel parts, particularly, parts of electronic apparatus, with which troubles caused by so-called “sulfide gas” mainly of H2S must be avoided. Release of the sulfide gas from the parts is effectively suppressed. The parts have high hardness and corrosion resistance, and can be produced with high finishing accuracy. The stainless steel parts are produced by processing a ferritic or a martensitic stainless steel of a specific alloy composition by forging and/or machining to the shape of the part followed by quenching and tempering, or quenching and tempering followed by machining to the shape of the part, and applying a solution of oxidative acid to the surface of the part so as to dissolve and remove sulfides existing on the surface of the part.
