InconelX-750 (UNS NO7750), different names for the same material.
Overview of the characteristics and application fields of Inconel It has good corrosion resistance and oxidation resistance below 980℃, high strength below 800℃, and good relaxation resistance below 540℃. It also has good formability and welding performance. This alloy is mainly used for Manufacturing of annular parts, structural parts, bolts and other parts for aero engines that work below 800°C and require high strength and corrosion resistance, and plane springs and coil springs that have medium or low stress and require relaxation resistance that work below 540°C. It can also be used to manufacture parts such as steam turbine blades.

GH4145 GH145 (China), NCl5FeTNbA (France), W.Nr.2.4669 NiCr15Fe7TiAl (Germany) NCF750 (Japan) InconelX-750 Metallographic structure Structure:
The structure of this alloy in the standard heat treatment state consists of γ matrix, Ti(C, N), Nb(C, N), M23C6 carbide and γ'[Ni3(Al, Ti, Nb)] Phase composition, γ' content is approximately 14.5%, which is the main strengthening phase of the alloy.
InconelX-750 process performance and requirements:
1. The alloy is easy to form at a forging temperature between 1220 and 950°C. The alloy is solution treated after a vigorous forming process.
2. The average grain size of the alloy is closely related to the degree of deformation and final forging temperature of the forging.
3. The alloy has good welding properties and can be used for various weldings. Aging treatment after welding can achieve strength close to the fully heat-treated state.
4. The heat treatment of parts is carried out in a sulfur-free neutral or reducing atmosphere to avoid vulcanization
