Abstract
Official abstract text for this publication.
Stainless steel alloys, and turbocharger kinematic components fabricated from such alloys (for example by sintering), are provided. A stainless steel alloy, or component fabricated therefrom, includes, by weight, about 20% to about 35% chromium, about 10% to about 15% nickel, about 10% to about 15% cobalt, about 10% to about 15% molybdenum, about 2.0% to about 4.0% carbon, about 0.4% to about 2.5% silicon, about 0.0% to about 1.0% niobium, and a balance of iron and other inevitable/unavoidable impurities.
