Key Advantages of Inconel X750 Square & Hex Bars
Precipitation-Hardened Yield Strength
Age-hardening produces fine gamma-prime precipitates, achieving exceptional yield strength up to 868 MPa for high-stress components.
High-Temperature Creep Resistance
Maintains structural dimensions and creep-rupture performance during continuous thermal operation up to 704 °C.
Cryogenic Toughness
Retains excellent impact strength and ductility in sub-zero and cryogenic liquid environments without embrittlement.
Relaxation & Fatigue Resistance
High fatigue limit and low relaxation rates make it ideal for high-stress springs and fasteners under dynamic loads.
Key Applications of Inconel X750 Square & Hex Bars
| Industry | Applications | Operational Benefit |
|---|---|---|
| Gas Turbines & Aerospace | Rotor bolts, turbine blades, lock wire hex fasteners, thrust hardware | Prevents high-temperature creep extension and bolt relaxation in extreme thermal stress zones. |
| Nuclear Power Plants | Fuel grid springs, control rod drive mechanism hex fittings, studs | Withstands high neutron irradiation exposure and pressurized water stress cracking. |
| Rocket Propulsion | Combustion chamber hardware, high-pressure liquid oxygen pump shafts | Retains ultra-high tensile property values and fracture toughness at cryogenic fluid temperatures. |
| Industrial Tooling | Hot-extrusion die inserts, high-temperature spring stock, square brackets | Delivers long production life under severe cyclic mechanical loads and elevated heat. |
Quality Testing & Inspection
As a certified Inconel X750 Square Bars and Hex Bars Exporter, Aurum Overseas enforces rigorous quality verification protocols on every production heat:
- Positive Material Identification (PMI): 100% XRF testing to verify exact 70.0% min Ni, 14.0–17.0% Cr, and 2.25–2.75% Ti composition.
- Heat Treatment Verification: Solution annealing and multi-stage precipitation age-hardening certification for gamma-prime phase uniformity.
