Inconel 718 is a precipitation-hardenable nickel-chromium superalloy that combines high yield strength with exceptional corrosion resistance at extreme temperatures. Unlike other superalloys, its specific chemistry prevents strain-age cracking during heating and cooling cycles. Our Inconel718 fasteners are strictly complies with the following chemical matrix to guarantee structural uniformity:
| Element | Nickel (Ni) | Chromium (Cr) | Iron (Fe) | Niobium (Nb) | Molybdenum (Mo) | Titanium (Ti) | Aluminum (Al) |
|---|---|---|---|---|---|---|---|
| Min % | 50.00 | 17.00 | Balance | 4.75 | 2.80 | 0.65 | 0.20 |
| Max % | 55.00 | 21.00 | — | 5.50 | 3.30 | 1.15 | 0.80 |
What standard we could provide for production of Inconel718
We manufacture and certify our Inconel 718 to meet the most stringent international, aerospace, and industrial specifications, the following are the standards we follow in our production, provided for your reference.
-
- AMS 5662 / AMS 5663 : Standard bars, forgings, and rings for aerospace applications.
- ASTM B637 : Precipitation-hardening nickel alloy rod, bar, and forging stock.
- NACE MR0175 / ISO 15156 : Certified for use in sour petroleum environments (H2S resistance).
- DIN EN 10269 : Steels and nickel alloys for fasteners with specified elevated temperature properties.
- EN 10204 3.1 Certification : Full chemical breakdown and mechanical destructive testing reports included with every shipment. We ensure finished Inconel718 products are in good condition.
What are the typical lead times for specialized Inconel 718 orders?
While the standard industry lead time for processing specialized nickel superalloys typically spans in 2weeks to 4weeks , our factory operates on a significantly faster timeline. Because we maintain a rolling inventory of certified Inconel 718 round bars directly in our warehouse, our standard lead times.
- In-Stock Products: Shipped within 24 to 48 hours .
- Custom Machined / Standard Inconel Fasteners: Completed within 2 to 3 weeks .
- Complex Specialty Forgings: Completed within 4 to 6 weeks
Products that we could manufacture with Inconel alloy718
We utilize Inconel 718 to manufacture a comprehensive range of industrial fasteners, including:
- Inconel 718 Bolts
- Inconel 718 Studs & Threaded Rods
- Inconel 718 Nuts & Washers
- Inconel 718 screws
- Custom Inconel CNC Machined Parts
How we avoid improper heat treatment ?
Inconel 718 only achieves its extreme strength through exact aging cycles. If the factory rushes or mismanages the heat treatment, the fasteners will experience premature fatigue, creep, or stress corrosion cracking. We prevent premature structural breakdown by executing computer-controlled thermal cycles in our in-house vacuum furnaces.
- 1. Solution Annealing (AMS 5662):
Heated to dissolve secondary phases and ensure a completely uniform grain structure. - 2. High-Speed Quenching:
Rapidly cooled using automated oil, water, or pressurized gas to lock the stabilized microstructure in place. - 3. Two-Step Aging (AMS 5663):
Soaked for 8 hours, and then furnace-cooled to 1150°F (621°C), and held for another 8 hours to fully precipitate the strengthening phase. - 4. 100% Quality Verification:
Every batch undergoes destructive laboratory analysis and mechanical testing to guarantee a strict 36–44 HRC hardness range.

We also provide custom Inconel 718 fabrication services.
We don't just manufacture Inconel718 bolts and Inconel718 screws or other standard fasteners, but can also machine, weld, and deliver complex, fully customized components from our raw bar stock. We leverage our in-house premium raw material inventory and advanced heavy-duty tooling to deliver custom-machined Inconel 718 components tailored directly to your engineering blueprints.
Our factory perform complex 3-axis, 4-axis, and multi-tasking CNC lathe machining. Our setups feature high-rigidity platforms and specialized ceramic cutters to maintain micro-tolerances (+/- 0.005mm) without causing structural work-hardening.
Frequently Asked Technical Questions (FAQs)
Q: Can your factory manufacture Inconel 718 fasteners to custom blueprint prints?
Yes. We operate a dedicated CNC and precision-forging factory line equipped to manufacture custom fasteners exactly to your engineering drawings. We routinely execute custom thread lengths, specialized head styles (such as 12-point spline or D-head bolts), and tightly-controlled dimensional tolerances required by aerospace prints.
Q: What quality certification documentation accompanies an Inconel 718 shipment?
Every shipment from our factory is fully traceable. We provide complete EN 10204 3.1 Material Test Reports (MTRs) detailing the exact mill chemical composition, mechanical destructive testing outcomes (tensile, yield, elongation), verified hardness testing results, and certified compliance with requested standards like AMS 5663 or ASTM B637.
Q: How do you prevent thread galling during installation of Inconel 718 fasteners?
Because nickel superalloys are highly prone to cold-welding and galling under high torque, we precisely control thread smoothness via post-heat-treat thread rolling. Depending on your assembly environment, we can also apply specialized industrial anti-galling coatings or silver/cadmium platings strictly executed to aerospace specifications.
