INCONEL® X750 ALLOY DESCRIPTION

Inconel® X750,is a nickel-chromium alloy made precipitation-hardenable by the additions of Titanium and aluminum, having high creep-rupture strength at high temperatures to about 130.0°F (700°C). It also has excellent properties down to cryogenic temperatures. Excellent corrosion and oxidation resistance and high strength at temperatures up to 1300°F.

APPLICATIONS

Bellows, gas turbine, rotor blades, springs, fasteners
