Alloy 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. The high nickel and chromium contents make the alloy resistant to a variety of both reducing and oxidizing media. The aluminum, in conjunction with the chromium, provides oxidation resistance at high temperatures. Solid-solution strengthening is imparted by the cobalt and molydenum.

Alloy in the field of hot corrosion environment such as sulfide, especially in the environment up to 1100 ℃ circulating oxidation and carbonization, has excellent corrosion resistance.The corrosion resistance combined with excellent mechanical properties, makes it particularly suitable for high temperature field. good transient and long term mechanical properties until the 1100 °C.
The combination of high strength and oxidation resistance at temperatures over 1800°F makes alloy 617 an attractive material for such components as ducting, combustion cans, and transition liner in both aircraft, and land based gas turbines. Because of its resistance to high-temperature corrosion, the alloy is used for catalyst-grid supports in the production of nitric acid, for heat-treating baskets, and for reduction boats in the refining of molybdenum. Alloy 617 also offers attractive properties for components of power-generating plants, both fossil-fueled and nuclear.
