Abstract
An austenitic stainless steel alloy and turbocharger kinematic components are provided. An austenitic stainless steel alloy includes, by weight, about 23% to about 27% chromium, about 18% to about 22% nickel, about 0.5% to about 2.0% manganese, about 1.2% to about 1.4% carbon, about 1.6% to about 1.8% silicon, about 0% to about 0.5% molybdenum, sulfur in an amount of less than about 0.01%, phosphorous in an amount of less than about 0.04%, and a balance of iron, and other inevitable/unavoidable impurities that are present in trace amounts. The turbocharger kinematic components are made at least in part using this stainless steel alloy.
