Overview:
Inconel 617 offers high temperature strength and great oxidation resistance. Excellent resistance to pitting and crevice corrosion and general corrosion in reducing and oxidizing conditions. It prevents carburization, spalling and aqueous corrosion. Alloy 617 is commonly used in aerospace and land base gas turbines, fossil fuels, catalyst grid support in acid processing and power production plants

Heat Treatment
Inconel 617 is normally used in the solution-annealed condition. That condition provides a coarse grain structure for the best creep-rupture strength. It also provides the best bend ductility at room temperature. Solution annealing is performed at a temperature of 2150 Degrees F for a time commensurate with section size. Cooling should be by water quenching or rapid air cooling.
Hot and Cold Forming
#1 – Hot rolled annealed and descaled. It is available in strip, foil and ribbon. It is used for applications where a smooth decorative finish is not required.
#2D – Dull finish produced by cold rolling, annealing and descaling. Used for deep drawn parts and those parts that need to retain lubricants in the forming process. #2B – Smooth finish produced by cold rolling, annealing and descaling. A light cold rolling pass is added after anneal with polished rolls giving it a brighter finish than 2D.
#BA- Bright annealed cold rolled and bright annealed
#CBA- Course bright annealed cold rolled matte finish and bright anneal
#2 – Cold Rolled
#2BA- Smooth finish produced by cold rolling and bright annealing. A light pass using highly polished rolls produces a glossy finish. A 2BA finish may be used for lightly formed applications where a glossy finish is desired in the formed part. Polished – Various grit finish for specific polish finished requirements.

Applications
The combination of high strength and oxidation resistance at temperatures over 1800 Degrees F makes Inconel 617 an attractive material for such components as ducting, combustion cans, and transition liner in both aircraft, and land based gas turbines. Because of its resistance to high-temperature corrosion, the alloy is used for catalyst-grid supports in the production of nitric acid, for heat-treating baskets, and for reduction boats in the refining of molybdenum. Inconel 617 also offers attractive properties for components of power-generating plants, both fossil-fueled and nuclear.
