Inconel X750 Strips

Product Details

A nickel-chromium alloy similar to INCONEL alloy 600 but made precipitation hardenable by additions of aluminum and titanium. It has good resistance to corrosion and oxidation along with high tensile and creep-rupture properties at temperatures to 1300°F (700°C). Its excellent relaxation resistance is useful for high-temperature springs and bolts. Used in gas turbines, rocket engines, nuclear reactors, pressure vessels, tooling and aircraft structures.

STANDARD PRODUCT FORMS
Sheet, strip, plate, round bar, flat bar, forging stock,hexagon, wire, tubing and extruded section.
