INCONEL 617 / UNS N06617

Common Trade Names: Inconel 617, Alloy 617, Nicrofer 617

INCONEL® alloy 617 (UNS N06617/W.Nr. 2.4663a) 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.

Available Product Forms:
Pipe, tube, sheet, strip, plate, round bar, flat bar, forging stock, hexagon, wire and extruded

Product description：

lnconel® 617 is a nickel-chromium-cobalt-molybdenum alloy with an exceptional combination of metallurgical stability, strength, and oxidation resistance at high temperatures. Resistance to oxidation is enhanced by an aluminum addition. The alloy also resists a wide range of corrosive aqueous environments. Used in gas turbines for combustion cans, ducting, and transition liners; for petrochemical processing; for heat-treating equipment; and in nitric acid production. Standard product forms are round, forging stock, extruded section, plate, sheet, strip, pipe, tube, and wire.

Product characteristics：

The alloy has excellent corrosion resistance in hot corrosion fields such as vulcanization environments, especially oxidation and carbonization environments with cycles up to 1100℃. These corrosion resistance combined with excellent mechanical properties make this alloy particularly suitable for high temperature applications. It has good instantaneous and long-term mechanical properties at high temperatures up to 1100℃.
