HY617 Material grades and equivalents

Inconel 617/ UNS N07617 / SEW VDIUV W.Nr.2.4663 NiCr23Co12Mo / AFNOR NC22KDA
HY 617 is a solid-solution, strengthened, nickel-chromium-cobalt- molybdenum alloy with an exceptional combination 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 HY617 an attractive material for such components as ducting, combustion cans, and transition 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

in. (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.

HY 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 substantial 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

HY 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.
