PROBLEM TO BE SOLVED: To provide a method for carburizing treatment for austenitic stainless steel by which its surface hardness can be improved without deteriorating the strength of a base metal and, moreover, a hard surface layer having corrosion resistance higher than that of the base metal can be formed. ;SOLUTION: This is a method for carburizing treatment for austenitic stainless steel in which, prior to carburizing treatment, austenitic stainless steel is held in a heating state in an atmosphere of gaseous fluorine, next, the temp. at the time of carburizing treatment is set to 400 to 680°C, and then, the carburizing treatment is executed. The austenitic stainless steel is composed of stable austenitic stainless steel contg. 1 to 6% molybdenum or stable austenitic stainless steel contg. 13 to 25% chromium, and a carburizing hardened layer having corrosion resistance higher than that of the base metal is formed by the carburizing treatment.;COPYRIGHT: (C)1997,JPO
