	PRODUCT DATA of Hastelloy X

Material	Hastelloy X
Product Datasheet	Hastelloy X
General Information	Hastelloy X is a nickel-base alloy used for combustor-liner parts, turbine-exhaust weldments, afterburner parts, and other parts requiring oxidation resistance and moderately high strength above 788 C. It is not hardenable except by cold working and is used in the solution-treated (annealed) condition. Hastelloy X is available in all the usual mill forms.
