Why Choose Our Inconel 617 Fasteners?

1. Built for Extreme Conditions

• Temperature Resistance: Sustain 1,200°C (2,192°F) without deformation.
• Corrosion Defense: Cr/Al oxide layer prevents scaling in sour gas (H2S), flue systems, and acidic environments.
• Certified Strength: Compliant with ASTM B166, ASME SB166, and EN 10095 standards.

2. Precision Engineering for Critical Applications

• Tight Tolerances: CNC-machined threads (±0.005mm) ensure perfect fits for API 6A/17D flanges.
• Surface Perfection: Electropolished finishes (Ra ≤1.6μm) minimize hydrogen permeation in PEM electrolyzers.
• Custom Solutions: EDM drilling and cold-forging for specialized needs like nuclear cooling channels.

3. Trusted Quality Assurance

• Zero-Defect Guarantee: UT/RT/ET testing detects flaws to ASME V standards.
• Full Traceability: Laser-marked MTRs validate Ni/Cr/Co content for every batch.
• Global Compliance: REACH, RoHS, and conflict-free sourcing documentation included.

• Scalable Output: 1,500+ tons/year capacity with JIT delivery to 70+ countries.

Package and Shipment

FAQs

Q: Are your fasteners compatible with API 6A wellhead equipment?

A: Yes. Our threading conforms to API 6A/17D specs for high-pressure applications.

Q: Do they resist hydrogen embrittlement in PEM electrolyzers?

A: Absolutely. Cold-forged variants pass ASTM F1624-06 tests with HEI ≤10%.

Q: Can you meet NACE MR0175 for sour gas environments?

A: While Inconel 617 performs well, we recommend alloy 625 for severe H2S exposure.
