Improved Cast Stainless Steel Alloys

At high temperatures, currently available cast stainless steel alloys used for engine component applications do not have the long-term stability of their original castings, and are lacking in their ability to resist deformation and cracking from extreme temperature changes. There is a need for high-strength, oxidation-resistant, and crack-resistant cast alloys for use in internal combustion engine components such as exhaust manifolds and turbocharger housings, gas-turbine engine components such as combustor housings, and other components that must function in extreme environments for prolonged periods of time.
