  • Inconel 617 is a solid-solution, strengthened, nickel-chromium-cobalt- molybdenum alloy with an exceptional co mbination of high-temperature strength and oxidation resistance. The alloy also has excellent resistance to a wide range of corrosive environments, and it is readily formed and welded by conventional techniques
  • The combination of high strength and oxidation resistance at temperatures over 1800°F (980°C) makes Inconel 617 an attractive material for such components as ducting, combustion cans, and transiti on liners in both aircraft and land-based gas turbines.

Corrosion Resistance

  • elevated temperatures, those elements cause the formation of a thin, subsurface zone of oxide particles.
  • The zone forms rapidly upon exposure to high temperatures until it reaches a thickness of 0.001 to 0.002(0.025 to 0.05 mm). The oxide zone provides the proper diffusion conditions for the formation of a
  • protective chromium oxide layer on the surface of the metal. It also helps to prevent spalling of the protective layer.
  • Inconel  617 has excellent resistance to carburization. Table 9 compares alloy 617 and some other carburization-resistant alloys in a gaseous carburizing environment at 2000°F (1095°C). The weight-gain measurements indicate the amount of carbon absorbed during the test period.
  • The composition of INCONEL alloy 617 includes ubstantial amounts of nickel, chromium, and aluminum for a high degree of resistance to oxidation and carburization at high temperatures. Those elements, along with the molybdenum content, also enable the alloy to withstand many wet corrosive environments.

Heat Treatment

  • Inconel  617 is normally used in the solutionannealed condition. That condition provides a coarse grain structure for the best creep-rupture strength. It also provides the best bend ductility at room temperature. Solution annealing is performed at a temperature of 2150°F (1175° C)for a time commensurate with section size.
  • Cooling should be by water quenching or rapid air cooling.
