Shanghai Hangbo Alloy Group Co., Ltd. is an ISO 9001:2015 certified manufacturer and global supplier of Inconel X-750 (UNS N07750), providing age-hardened bars, seamless tubes, and plates for aerospace fasteners, nuclear springs, and gas turbine components.
Quick Answer: What Is Inconel X-750?
Inconel X-750 (UNS N07750, W.Nr. 2.4669) is a precipitation-hardenable nickel-chromium alloy strengthened by additions of aluminum, titanium, and niobium through the γ′ (gamma prime) phase. After age hardening, it achieves tensile strengths exceeding 1000 MPa while retaining good ductility and oxidation resistance up to 980°C (1800°F). It is the alloy of choice for high-temperature springs, bolting, and structural members in gas turbines and nuclear reactors.
Key standards: AMS 5542 (sheet/strip), AMS 5582 (tube), AMS 5667 / 5668 / 5669 (bar by condition), ASTM B637

Frequently Asked Questions (FAQ)
What is the difference between Inconel X-750 Condition A, C, and H?
The conditions refer to different age-hardening heat treatment schedules:
- Condition A (AMS 5668): 8h at 704°C — highest strength, used for bolts and springs
- Condition C (AMS 5669): Solution anneal at 1163°C + 24h at 843°C + 20h at 704°C — best overall combination of strength and ductility for structural applications
- Condition H (proprietary): Optimised for specific spring-relaxation resistance
Is Inconel X-750 suitable for nuclear reactor use?
Yes. Inconel X-750 is widely used in light water reactor (LWR) internals, including holddown springs and baffle bolts. Shanghai Hangbo can supply material with documentation compliant with nuclear industry requirements.
Can Shanghai Hangbo supply X-750 in the fully age-hardened condition?
Yes. We supply all standard AMS conditions (annealed, Condition A, Condition C). Please specify the required condition when requesting a quote.
