INCONEL® alloy X-750


Inconel X-750 alloy is mainly based on γ”[Ni3(Al, Ti, Nb)] phase aging strengthening nickel base superalloy, has good corrosion resistance and oxidation resistance below 980℃, has high strength below 800℃, has good relaxation resistance below 540℃. It also has good formability and welding performance. The alloy is mainly used to manufacture plane springs and coil springs which are resistant to relaxation and require high strength when the aero-engine works below 800℃. It can also be used to manufacture turbine blades and other parts. We can supply sheet, strip, bar, forging, ring, wire and pipe.

Inconel X-750 is a precipitation-hardenable alloy which has been used in applications such as high temperature structural members for gas turbines, jet engine parts, nuclear power plant applications, heat-treating fixtures, forming tools, and extrusion dies. The alloy is highly resistant to chemical corrosion and oxidation and has high stress-rupture strength and low creep rates under high stresses at temperatures up to 1500°F (816°C) after suitable heat treatment.


Conventional machining techniques used for iron based alloys may be used. This alloy does work-harden during machining and has higher strength and “gumminess” not typical of steels. Heavy duty machining equipment and tooling should be used to minimize chatter or work-hardening of the alloy ahead of the cutting.

Corrosion resistance:

Inconel X-750 has excellent resistance to chloride ion stress-corrosion cracking. It exhibits satisfactory resistance to numerous oxidizing environments. The alloy has similar corrosion resistance to alloy 600 in many media.

Application range and field:

Nuclear reactors, Gas turbines, Rocket engines, Pressure vessels, Aircraft structures.
