Inconel X750 (For Springs)
X750 is a Nickel-Chromium alloy made precipitation hardenable by additions of Al and Ti, having creep-rupture strength at high temperatures to about 700°C (1290°F). It is widely used for high temperature conditions but is not as strong as Nimonic 90. It can be used for any TSMC spring product such as wave springs, retaining rings and compression springs.
Inconel X750 is also known as Nicrofer 7016, Superimphy 750, Haynes X750, Pyromet X750, and Udimet X750.
