PRODUCT DATA of Inconel 617
MaterialInconel 617
Product DatasheetInconel alloy 617
General InformationAlloy 617 is a solid-solution, nickel-chromium-cobalt-molydenum alloy with an exceptional combination of high-temperature strength and oxidation resistance. The alloy also has excellent resistance to a wide range of corrosive environment, and it is readily formed and welded by conventional techniques.
Use in SpacecraftUsed in aircraft, and land based gas turbines. Especially useful at temperatures in excess of 980 C
