Abstract

A stable austenitic stainless steel consists of the following .C.trace-0.12% .Mn.5.0-8.5% .Si.trace-2.0% .Cr.15.0-17.5% .Ni.3.0-6.5% .Cu.0.75-2.5% .N.trace-0.1% .Fe and impurities the remainder,. the constituents being controlled so that the martensite-forming characteristic is less than 10% according to the following formula % martensite=358-221 (%C+%N)-6.42 (%Mn)-11.7 (%Cr)-12.7 (%Ni)-22.7 (%Cu) and the delta ferrite-forming characteristic is less than 10% according to the formula % delta ferrite potential=%Cr+1.5 (%Si)-0.87[30(%C+%N)+%Ni+0.5(%Mn) +0.3(%Cu)]+1 and wherein the amount of Cu is controlled so that it does not exceed 3.85-0.18(%Mn).
