Exotic Alloys Alloy X750 Fittings Overview
Zeon Exports supplies Exotic Alloy X750 (Inconel, UNS N07750) fittings – elbows, tees, reducers and stub ends – a precipitation-hardening nickel-chromium superalloy with excellent creep-rupture strength and relaxation resistance at elevated temperatures up to 700°C.
Exotic Alloy X750 (Inconel) Fittings connect and direct piping runs in gas turbine, aerospace and nuclear systems. Its aluminum and titanium age-hardening gives outstanding creep-rupture strength and relaxation resistance from cryogenic temperatures up to roughly 700°C, making it a preferred choice for critical high-temperature, high-stress components.
- Age-hardened via aluminum and titanium for high strength and creep resistance
- Typical tensile 1103–1241 MPa, yield 758–900 MPa (single-aged)
- EN 10204 3.1 certified, export-ready worldwide
