Beschreibung
Zusammenfassung:	Disclosed is an austenitic stainless steel alloy that includes or consists of, by weight, about 23.0% to about 25.0% chromium, about 8.5% to about 10.0% nickel, about 0.5% to about 2.0% manganese, about 0.8% to about 1.0% niobium, about 0.5% to about 1.5% silicon, about 0.35% to about 0.45% carbon, about 0.2% to about 0.28% nitrogen, a balance of iron, and other inevitable/unavoidable impurities that are present in trace amounts. The elements zirconium and sulfur are excluded from the alloy beyond impurity levels. Turbocharger turbine housings made of the stainless steel alloy, and methods of making the same, are also disclosed. The stainless steel alloy is suitable for use in turbocharger turbine applications for temperatures up to about 1,020° C.
