Abstract:
The invention provides an austenitic ductile cast iron alloy composition including about 2.2% to about 2.4% by weight carbon; about 3.5% to about 4.0% by weight silicon; about 28% to about 29% by weight nickel; about 2.5% to about 3.0% by weight chromium; about 0.9% to about 1.1% by weight molybdenum; and greater than about 50% iron, wherein percentages are based on the overall weight of the composition. The invention further provides articles, such as turbocharger housings, prepared using the inventive alloys.
