Product Description
The Inconel X-750 nickel alloy is similar to Inconel alloy 600 but made precipitation hardenable by adding aluminum and titanium and thereby shows excellent resistance to high temperature corrosion and oxidation along with high tensile and creep-rupture strength, relaxation resistance as well as good fabricating and welding properties.
High strength at temperatures to 1500°F (816°C) after suitable heat treatment
Creep-rupture strength at high temperatures to about 700°C (1290℉)
High tensile and creep-rupture properties
Resistance to a wide variety of industrial corrosives under both oxidizing and reducing conditions
Excellent workability including machinability and welding
Resistance to chloride ion stress-corrosion cracking
Precipitation hardenable
The alloy X-750 also has outstanding mechanical properties down to cryogenic temperatures. With such properties, the nickel-chromium alloy is mainly used for high-temperature springs and bolts, gas turbine blades, rocket engines, abrasion wheels, high pressure vessels, etc.

Inconel X-750 Application:

  • Gas turbines
  • Jet engine parts
  • Nuclear power plant applications
  • Heat-treating fixtures
  • Forming tools and extrusion dies
  • Pressure vessels
  • Aircraft structures
