Inconel X750 Characteristic as below:
Inconel X750 is a precipitation-hard-enable 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.
Inconel X750 Machinability:
-
Conventional machining techniques used for iron based alloys may be used. This alloy does
-
work-harden during machining and has higher strength and “gumminess” not typical of steels. Heavy duty machining equipment and tooling should be used to minimize chatter or work-hardening of thealloy ahead of the cutting.
Inconel X750 Corrosion resistance:
-
Inconel X750 has excellent resistance to chloride ion stress-corrosion cracking. It exhibits satisfactory resistance to numerous oxidizing environments. The alloy has similar corrosion resistance to alloy 600 in many media.
Inconel X750 Application range and field:
-
Nuclear reactors
-
Gas turbines Rocket engines Pressure vessels Aircraft structures
