ABSTRACT:
An austenitic stainless steel alloy has a composition of about 6 to about 13 percent aluminum, about 7 to about 34 percent manganese, about 0.2 to about 2.4 percent carbon, 0.4 to about 1.3 percent silicon, about 0 to about 6 percent chromium, about 0.5 to about 6 percent nickel, and the balance essentially iron. The relative quantities of the foregoing elements are selected from these ranges to produce a volume percent of ferrite structure in the alloy in the range of about 1 percent to about 8 percent. The volume percent of ferrite is determined by the empirical formula ##EQU1##
