Inconel® Alloy 617

Inconel® Alloy 617 / 2.4663 / UNS N06617

Inconel® Alloy 617 is a nickel-chromium-cobalt-molybdenum alloy with an excellent combination of high strength, metallurgical stability, and oxidation resistance at high temperatures. The addition of aluminum significantly enhances the oxidation resistance, making this alloy exceptionally suitable for prolonged exposure to extreme heat.

Additionally, Inconel® 617 is highly resistant to aqueous corrosive environments, making it widely applicable in both thermal and chemical applications.

Properties of Inconel® Alloy 617

Inconel® 617 excels with its outstanding performance at high temperatures, maintaining its strength, structure, and resistance to oxidation. The presence of chromium, cobalt, and molybdenum creates a robust matrix with high mechanical reliability. The addition of aluminum enhances the formation of a stable oxide layer, providing extra protection during prolonged heating.

In addition to oxidation and heat resistance, Inconel® 617 also offers good resistance to various chemically aggressive and aqueous environments, making it suitable for applications where both thermal and chemical stresses are present.

The alloy is highly workable and can be welded and formed using standard techniques, making it applicable in a wide range of industrial applications.

Applications of Inconel® Alloy 617

Inconel® Alloy 617 is widely used in environments where extreme heat, corrosion, and structural stability are required. Examples of applications include:

  • Gas turbines, particularly for combustion chambers and cans

  • Petrochemical processing plants

  • Heat treatment equipment and furnaces

  • Nitric acid production equipment

  • Components in power plants and high-temperature systems

The exceptional performance of Inconel® 617 at high temperatures and in corrosive environments makes it an ideal choice for long-lasting and demanding industrial processes.

Inconel® Alloy 617 is the alloy for extreme temperatures, chemical resistance, and structural reliability all in one material.
