Alloy 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.

Characteristics
 

The Inconel X-750 offers excellent corrosion and oxidation resistance up to 980 ° C, high strength up to 800 ° C, good relaxation resistance up to 540 ° C, as well as excellent formability and welding properties, and excellent mechanical properties at low temperatures.

Applications

The alloy has good corrosion resistance and creep fracture strength under high temperature environment, good mechanical properties, widely used, and has sufficient strength and corrosion resistance and oxidation resistance below 980ºC.
1. Made springs and bolts working at high temperature;Rotor blades, impellers and other structural parts on gas turbines;
 
3. Thrust reverse device on the aircraft;
4. Large high-pressure vessels;
5. Elastic air seal piece, elastic seal die piece, rubber mechanical electric heating blade.
