UNS N07750 Pipe

Inconel UNS N07750 Pipe Features

UNS N07750 alloy pipe is mainly a nickel-based superalloy which is age-strengthened with γ[Ni3(Al, Ti, Nb)] phase. It has good corrosion resistance and oxidation resistance below 980℃, and below 800℃ It has high corrosion resistance. It has good relaxation resistance below 540°C, as well as good formability and weldability. This alloy is mainly used for the manufacture of aircraft engines that work below 800°C and require high strength. . Springs can also be used to manufacture steam turbine turbine blades and other parts, such as plates, strips, bars, forgings, rings, wires, pipes, etc.

UNS N07750 Pipe Heat Treatment Process

The solution heat treatment system for plates, strips and pipes in the supply state is 980℃±15℃, air cooling. For the intermediate heat treatment system of materials and parts, the following processes can be selected for heat treatment.
Annealing: 955～1010℃, water cooling.
Annealing of welded parts before welding: 980℃, 1h.
Stress relief annealing of welded parts: 900℃, moisturizing for 2h.
Stress relief annealing: 885℃±15℃, 24h, air cooling.
