Inconel® X750 is a nickel chromium alloy made precipitation hardenable by the additions of Titanium and aluminum. It has been used in high temperature structural parts such as QAS turbines, jet engine components, nuclear power plant applications, heat treatment fixtures, forming tools and extrusion dies.The alloy is highly resistant to chemical corrosion and oxidation, and has high stress endurance strength and low creep rate at high stress conditions up to 1500°F(816°C) after proper heat treatment.Inconel X-750 can be processed using traditional techniques for iron-based alloys.This alloy works hard during processing and has higher strength and "stickiness" than typical steels.Heavy machining equipment and tools should be used to reduce the flutter or work hardening of the alloy before cutting the tool.Inconel X-750 Corrosion Resistant Inconel X-750 has excellent resistance to chloride ion stress corrosion cracking.It shows satisfactory oxidation resistance in various oxidizing environments.The alloy exhibits similar corrosion resistance to alloy 600 in many media.
