Shanghai Hangbo Alloy Group Co., Ltd. is an ISO 9001:2015 certified manufacturer and global supplier of Inconel 617 (UNS N06617), providing high-quality round bars, seamless tubes, and plates for gas turbine, aerospace, and high-temperature industrial applications.
Quick Answer: What Is Inconel 617?
Inconel 617 (UNS N06617, W.Nr. 2.4663) is a nickel-chromium-cobalt-molybdenum alloy with exceptional creep strength and oxidation resistance at temperatures above 900°C (1650°F). It uniquely combines the solid-solution strengthening from molybdenum and cobalt with an alumina-forming oxide layer, making it one of the most capable alloys for the hottest sections of gas turbines and industrial furnaces. It is approved for use in ASME Boiler and Pressure Vessel Code applications up to 980°C.
Key standards: ASTM B166 (bar), ASTM B167 (tube), ASTM B168 (plate), AMS 5887 (sheet), ASME SB-166 / SB-167 / SB-168

Frequently Asked Questions (FAQ)
Is Inconel 617 the same as alloy 617?
Yes. "Alloy 617" and "Inconel 617" refer to the same material — UNS N06617. "Inconel" is a registered trademark of Special Metals Corporation. Different manufacturers market this alloy under other trade names (e.g., Nicrofer 5520Co), but the composition and performance are equivalent.
Why is Inconel 617 preferred over Inconel 625 for very high-temperature structural applications?
While Inconel 625 is excellent for corrosion resistance, its strength drops significantly above 800°C. Inconel 617's cobalt and molybdenum additions maintain significantly higher creep-rupture strength at 900–1000°C, making it the better choice for hot-section gas turbine components.
Does Inconel 617 meet ASME pressure vessel code requirements?
Yes. Inconel 617 is listed in ASME Section II Part D for use in pressure vessels and piping at elevated temperatures, with allowable stress values provided up to 980°C.
