Key Advantages of UNS N07750 Round Bars
Super High Strength
Special heat treatments trigger added titanium and aluminum to harden the metal internally, boosting its overall strength to handle heavy loads.
Handles High Temperatures
Maintains structural integrity and high yield strength under continuous heat exposure up to 704°C without weakening.
Resists Corrosion & Oxidation
Built with high nickel and chromium levels to protect against chemical breakdown, rusting, and scaling in harsh environments.
Cryogenic Reliability
Retains excellent toughness and ductility in sub-zero and freezing temperatures without turning brittle.
Resists Relaxation
Resists shape distortion and stress relaxation over long periods, making it ideal for high-stress industrial springs and hold-down bolts.
Key Applications of Inconel X750 Round Bars
| Industry Sector | Typical Components | Operating Conditions |
|---|---|---|
| Aerospace & Defense | Thrust reversers, jet engine hardware, and turbine blades | Extreme thermal stress, high vibration, and mechanical fatigue |
| Nuclear Energy | Springs, control rod drive mechanisms, and grid fasteners | High neutron exposure, elevated heat, and corrosive pure water |
| Gas Turbines | Rotor bolts, bucket lock pins, and high-temperature studs | Continuous heat up to 704°C and high centrifugal forces |
| Oil & Gas Processing | Valve stems, high-pressure springs, and blowout preventer parts | Sour gas (H₂S) exposure, high pressure, and chloride environments |
| Industrial Processing | Forming dies, extrusion arms, and pressure vessel bolting | Severe mechanical loading at elevated operating temperatures |
Quality Testing & Inspection
Every batch of ASTM B637 UNS N07750 Round Bars supplied by Aurum Overseas undergoes strict quality testing:
- Positive Material Identification (PMI): XRF testing verifies chemical composition to ensure precise nickel, chromium, titanium, and aluminum ratios.
- Ultrasonic Testing (UT): Evaluates internal sound quality of forged bars per ASTM A388 to prevent sub-surface defects.
- Mechanical Tensile & Hardness Testing: Confirms yield strength, tensile strength, and elongation compliance with ASTM B637 standards.
- Grain Size & Metallographic Evaluation: Verifies proper solution annealing and precipitation heat treatment phase distribution.

Frequently Asked Questions
Inconel X750 includes titanium and aluminum additions that allow precipitation hardening for significantly higher tensile strength, whereas Inconel 600 is a non-hardenable solid-solution alloy.
ASTM B637 covers precipitation-hardening nickel-alloy rods, bars, forgings, and forging stock intended for high-temperature service.
Yes, Inconel X750 retains high strength, excellent impact resistance, and ductility at sub-zero temperatures without becoming brittle.
Machining Inconel X750 requires heavy-duty machinery, slow cutting speeds, rigid tooling, and abundant coolant to manage work hardening.
All exports include EN 10204 3.1 Mill Test Certificates verifying heat numbers, chemical content, tensile test values, PMI results, and ultrasonic inspection clearance.
