About Inconel X-750
Precipitation-hardened Inconel X-750 for springs, fasteners and gas-turbine components.
Inconel X-750 (UNS N07750) is an age-hardenable nickel-chromium alloy strengthened by titanium and aluminium additions to Inconel 600 chemistry. It retains high strength and relaxation resistance to about 700 °C and remains oxidation resistant to 980 °C, which makes it the standard material for turbine springs, bolting, seals and rotor blade retention parts.
Steelco Metal & Alloys stocks Inconel X-750 (UNS N07750) in Mumbai, India as a stockist, importer and exporter, and ships to 40+ countries. Every dispatch carries EN 10204 3.1 (3.2 on request) mill test certificates, PMI verification and is open to third-party inspection.
