UNS Number N06617

Inconel 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.

Machining and Fabrication with Inconel 617:

Inconel 617 can be formed using all conventional techniques. It is forged at 1010 to 1205°C (1850 to 2200°F). Inconel 617 is welded using gas-tungsten arc welding, shielded metal-arc welding, gas metal-arc welding, and submerged-arc welding methods. It is hot worked at 927 to 1205°C (1700 to 2200°F). It can be cold worked using standard tooling. It is annealed at 1177°C (2150°F) followed by cooling. It can be hardened by cold working.
