Nickel Alloy 617 is a nickel-chromium-cobalt alloy that is known primarily for its exceptional metallurgical stability. Also sold under the brand name Inconel® 617, this alloy brings a wide variety of other outstanding properties to users, including:
Resistance to oxidation at high temperatures, thanks to added aluminum
Good resistance to a wide range of corrosive aqueous environments
Resistant to a number of different damaging reducing and oxidizing media
Cobalt and molybdenum impart a solid-solution strengthening
Easy to fabricate
Ease of joining through most conventional welding techniques
Nickel Alloy 617 offers customers a unique chemical composition that includes:
Ni 44.5%
Cr 20-24%
Co 10-15%
Mo 8-10%
Fe 3% max
Si 1% max
Al .8-1.5%
Ti 0.6% max
Many industries around the globe rely on Inconel® 617 or Nickel Alloy 617 for a number of different processes. The alloy is found in ducting, combustion cans, chemical production, heat-treating baskets, power-generating plants (both fossil fuel and nuclear), and gas turbines both on land and in the air.
Inconel® 617 and Nickel Alloy 617 can be sourced via Jiangsu HYT. Various forms include pipe, tube, sheet, plate, round bar, flat bar, forging stock, hexagon, wire, and extruded section.
We stock and sell Nickel Alloy 617 and Inconel® 617 in Pipe, tube, sheet, strip, plate, round bar, flat bar, forging stock, hexagon, wire and extruded section.

Fabrication and Heat Treatment of Nickel Alloy 617 Inconel® 617
Machinability
Inconel 617 is machined using conventional machining methods which are usually used for iron-based alloys. Machining operations are performed using commercial coolants. High-speed operations such as grinding, milling or turning, are performed using water-base coolants.
Forming
Inconel 617 can be formed using all conventional techniques.
Welding
Inconel 617 is welded using gas-tungsten arc welding, shielded metal-arc welding, gas metal-arc welding, and submerged-arc welding methods.
Heat Treatment
Inconel 617 is heat treated by annealing at 1177°C (2150°F) followed by quenching in water or cooling in air for thinner sections.
Forging
Inconel 617 is forged at 1010 to 1205°C (1850 to 2200°F).
Hot Working
Inconel 617 is hot worked at 927 to 1205°C (1700 to 2200°F).
Cold Working
Inconel 617 can be cold worked using standard tooling.
Annealing
Inconel 617 is annealed at 1177°C (2150°F) followed by cooling.
Hardening
Inconel 617 can be hardened by cold working.
