Inconel 617

Inconel 617 High Creep Strength Alloy

Inconel® 617

UNS N06617 | W.Nr. 2.4663 | Alloy 617

Inconel 617 is a solid-solution, nickel-chromium-cobalt-molybdenum alloy. It offers an exceptional combination of high-temperature oxidation resistance and high creep-rupture strength. It is capable of withstanding extreme temperatures above 1800°F (980°C).

  • Formas comunes: Plate, Sheet, Bar, Pipe, Forgings.
  • Característica clave: Excellent creep-rupture strength at temperatures > 1800°F.
  • Chemical Composition: Enriched with Cobalt and Molybdenum.
  • Soldabilidad: Good weldability by conventional techniques.
Why Choose Inconel 617?

Inconel 617 is often the final choice when other alloys lack the structural integrity at extreme temperatures. The substantial addition of Cobalt y Molibdeno provides solid-solution strengthening, allowing it to support loads at temperatures where other alloys would fail due to creep.

Alta resistencia a la fluencia

Designed specifically for service above 1800°F (980°C), making it superior to Inconel 600 and 601 in structural applications under load.

Resistencia a la oxidación

The high Chromium and Aluminum content provides excellent resistance to oxidation and carburization, similar to Inconel 601.

Metallurgical Stability

The alloy remains stable and retains high ductility even after prolonged exposure to elevated temperatures.
