Abstract
Disclosed is an austenitic stainless steel alloy that includes or consists of, by weight, about 24% to about 26% chromium, about 11% to about 13% nickel, about 4.5% to about 5.5% manganese, about 1.3% to about 1.7% silicon, about 1.2% to about 1.6% niobium, about 0.40% to about 0.50% carbon, about 0.2% to about 0.4% nitrogen, and a balance of iron with inevitable/unavoidable impurities. The alloy is suitable for use in turbocharger turbine applications for temperatures up to about 1050° C.
