Alloy 617
UNS N06617
Description
Alloy 617 is a solid-solution, nickel-chromium-cobalt-molybdenum alloy with an exceptional combination of metallurgical stability, strength, and oxidation resistance at high temperatures. The enhanced oxidation resistance is attributed to the aluminium in conjunction with the chromium. It also has excellent resistance to a variety of both reducing and oxidizing media due to the high nickel and chromium contents. And those elements with the molybdenum enable the alloy to withstand many wet corrosive environments. Alloy 617 is an excellent choice for high temperature applications in various industries such as aerospace and power generation markets, and petrochemical plants.
