Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a high corrosion resistance high strength stainless steel suppressing stress corrosion crack, irradiation induced stress corrosion crack, crevice corrosion and the like in circumstance of being exposed to neutron irradiation environment.SOLUTION: The high corrosion resistance high strength stainless steel is an austenite stainless steel and has a chemical composition consisting of C of 0.04 mass% or less, Mn of 1.0 to 2.0 mass%, N of 9.0 to 13.0 mass%, Cr of 17.0 to 20.0 mass%, Ta of 13 times as C and 0.50 to 0.65 mass%, and the balance Fe and Nb with inevitable impurities. It has an austenite average crystal grain size number defined in JIS G 0551 of 10.0 to 13.0.
