1. A turbocharger kinematic component consisting of:
an austenitic stainless steel alloy, wherein the austenitic stainless steel alloy consists of, by weight:
about 23% to about 27% chromium,
19.5% to 20.5% 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 0.2% to about 0.4% nitrogen,
about 0% to about 0.5% molybdenum, and
a balance of iron, and unavoidable impurities that are present in trace amounts.
