ALLOY X-750

Nickel alloy

UNS N07750

Alloy X-750 is a precipitation-hardening nickel-chromium superalloy that offers excellent mechanical strength and good corrosion resistance up to high temperatures. It retains its tensile, fatigue, and creep properties in severe environments, while exhibiting good resistance to oxidation. This alloy is particularly well-suited for applications requiring high mechanical strength at elevated temperatures over long service life spans.
