Key Advantages
High Yield Strength
Age-hardening with Titanium and Aluminum provides over 868 MPa yield strength for heavy tension bolting.
Resists Heat Relaxation
Holds spring tightness and clamping force under continuous high heat without loosening or stretching.
Corrosion & Oxidation Resistance
High 70% Nickel and 14–17% Chromium prevent scaling and environmental cracking in hot steam lines.
Smooth & Secure Threading
Precision roll-threaded construction prevents thread stripping and jamming under heavy installation torque.
Quality Testing & Inspection
Aurum Overseas subjects every order to strict quality control processes to ensure compliance with international fastener standards and client specifications:
- Chemical Heat Verification (PMI): Spectro / XRF material analysis verifying exact elemental chemistry against ASTM standards.
- Thread Pitch & Gage Inspection: Go/No-Go thread gage and optical comparator testing ensuring class 2A/3A and 6g pitch tolerances.
- Mechanical Property Certification: Factory batch verification of tensile, yield strength, and elongation supported by EN 10204 3.1 MTRs.
- Optional Third-Party Testing: Ultrasonic (UT), Dye Penetrant (DPI), or Proof Load testing provided upon client project request.

Frequently Asked Questions
Inconel X750 gets its high strength through age-hardening heat treatments, where Titanium and Aluminum precipitate to form a gamma prime matrix phase that locks the structure against mechanical deformation.
Yes. Inconel X750 maintains good ductility, toughness, and mechanical strength at sub-zero and cryogenic temperatures while resisting brittle fracture.
There is no physical or technical distinction. Both terms refer to continuously threaded bar stock used for stud bolting, structural anchoring, and flange clamping.
