【Abstract】 Based on the technical method and technical parameter of 21-4N valves, a satisfactory method applied to ion-carbonitriding the stainless steels valve was described. By this treatment, it is possible to obtain stainless steels valves of high hardness, compact and corrosion-resistance, as the valves dimension is accurately held.更多还原
