Technical Data Sheet
Alloy 617/ Inconel 617 ® (UNS N06617) is a nickel-chromium-cobalt-molybdenum alloy with an exceptional combination of high-temperature strength and oxidation resistance. The high nickel and chromium contents make the alloy 617 resistant to a variety of both reducing and oxidizing environments, while the aluminum with the chromium provides oxidation resistance at high temperatures. Those elements with the molybdenum enables the alloy to withstand many wet corrosive environments.
