Inconel alloy 783 (UNS R30783/U.S. Patent 5,478,417), is an oxidation-resistant, low expansion, nickel-cobalt-iron alloy with aluminum, chromium, and niobium additions. The new alloy is of considerable interest to aircraft gas turbine engine designers and materials engineers for containment and clearance control components such as rings, casings, shrouds and seals for compressors, turbines and exhaust systems.
The three-phase age hardenable alloy offers a range o improvements for these applications over alternative alloys in current use: A coefficient of thermal expansion approximately 20% lower than that of Inconel alloy 718. Excellent resistance to oxidation, demonstrated in cyclic tests, at temperatures up to and beyond 1300°F (704°C).
Resistance to SAGBO (stress accelerated grain boundary oxidation) comparable to that of Inconel alloy 718, and significantly better than that of Inconel alloy 909. A density of 0.282 lb/in3 (7.81 g/cm3), 5% less than Inconel alloy 718 or Inconel alloy 909, contributing to an important potential improvement in strength-to-weight ratios.
Manufacturing/processing characteristics comparable to those of Inconel alloy 718, and less limiting than those of Inconel alloy 909.

Inconel 783 Fabrication and Heat Treatment
Inconel alloy 783 has good fabricability and can be formed, machined, and welded using all the traditional procedures for nickel alloys. This alloy’s reactions are similar to that of Inconel 718
Inconel 783 Machinability
Inconel alloy 783 can be readily machined using the conventional practices for high-strength nickel alloys. In case of rough machining, the material has to be machined in the annealed condition.
Inconel 783 Hot Forming
The temperature range for hot forming of Inconel alloy 783 is from 927°C to 1121°C (1700°F to 2050°F).
Inconel 783 Heat Treatment
To heat treat this super alloy, the material has to solution annealed at 1121°C (2050°F) for 1 h, and air cooled. This should be followed by beta aging at 845°C (1550°F) for 4 h and air cooled to room temperature. Next the material is age hardened at 720°C (1325°F) for 8 h, furnace cooled at 55°C (100°F) for 1 hr to 620°C (1150°F) for 8 h and air cooled.
