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.
First claim
Opening claim text (preview).
What is claimed is: 1. A turbocharger kinematic component configured for operation at temperatures up to about 1050° C., comprising: a sintered iron-based alloy, wherein the sintered iron-based alloy comprises, 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 inevitable/unavoidable impurities, wherein the element manganese is excluded beyond impurity levels. 2. The turbocharger kinematic component of claim 1 comprising about 22% to about 33% chromium. 3. The turbocharger kinematic component of claim 1 comprising about 24% to about 31% chromium. 4. The turbocharger kinematic component of claim 1 comprising about 26% to about 29% chromium. 5. The turbocharger kinematic component of claim 1 comprising about 11% to about 14% nickel. 6. The turbocharger kinematic component of claim 1 comprising about 12% to about 13% nickel. 7. The turbocharger kinematic component of claim 1 comprising about 11% to about 14% cobalt. 8. The turbocharger kinematic component of claim 1 comprising about 12% to about 13% cobalt. 9. The turbocharger kinematic component of claim 1 comprising about 2.5% to about 3.5% carbon. 10. The turbocharger kinematic component of claim 1 comprising about 0.3% to about 0.7% niobium. 11. The turbocharger kinematic component of claim 1 , wherein the turbocharger kinematic component is selected from the group consisting of: a vane and unison ring assembly of a variable geometry turbocharger, and a waste-gate assembly of a turbocharger.
