Abstract
A terrific stainless steel alloy and turbocharger kinematic components are provided. A ferritic stainless steel alloy includes or consists of, by weight, about 20% to about 35% chromium, less than about 2% nickel (i.e., from 0% to about 2%), about 1% to about 4% carbon, about 1.5% to about 1.9% silicon, less than about 0.4% nitrogen (i.e., from 0% to about 0.4%), about 0.5% to about 15% molybdenum, less than about 1% niobium (i.e., from 0% to about 1%) 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.
