Inconel fasteners, made from high-performance nickel-chromium-based alloys, are used in extreme environments where stainless steel would fail—such as high-temperature, high-pressure, and corrosive applications. These fasteners are available in various grades including Inconel 600, 625, 718, and 800, and are used in aerospace, chemical processing, marine, and power generation industries. This article explores Inconel fasteners pricing by type, grade, size, and global sourcing trends to help buyers make informed procurement decisions.
Inconel Fasteners Price by Grade
Prices vary significantly depending on the alloy grade, mechanical strength, and corrosion resistance.
| Inconel Grade | Common Use | Price Range (USD/kg) |
|---|---|---|
| Inconel 600 | Heat exchangers, nuclear components | $60 – $75 |
| Inconel 625 | Chemical plants, marine hardware | $75 – $95 |
| Inconel 718 | Aerospace, gas turbines | $80 – $110 |
| Inconel 800/825 | Petrochemical piping | $65 – $85 |
Common Types of Inconel Fasteners
Inconel fasteners are available in a wide variety of configurations, and pricing varies by type and size:
| Fastener Type | Typical Sizes | Price Range (USD/pc) |
|---|---|---|
| Hex Bolts | M6 – M30 | $2 – $50 |
| Stud Bolts | M8 – M36 | $3 – $75 |
| Socket Head Cap Screws | M4 – M20 | $1.50 – $25 |
| Nuts | M6 – M36 | $0.80 – $20 |
| Washers | Standard metric/inch | $0.30 – $5 |
Factors Influencing Price
Several variables affect the final cost of Inconel fasteners:
• Grade of Alloy: Higher grades like Inconel 718 are more expensive due to complex composition and aerospace certifications.
• Heat Treatment: Fasteners requiring annealing, solution treatment, or aging are priced higher.
• Quantity Ordered: Bulk orders receive discounted pricing, while small batches cost more per piece.
• Certifications: Fasteners with NACE, ASTM, or aerospace approvals carry a premium.
• Origin: USA and EU-produced fasteners tend to be more expensive than those made in India or China.

Buying Tips
• Request 3.1 or 3.2 Mill Test Certificates for alloy verification.
• Ask if fasteners are passivated or pickled—especially for marine or chemical use.
• Confirm thread standards (UNC, UNF, metric) match your application.
• For critical applications, insist on NACE MR0175 or ISO 15156 compliance.
Related Questions
Are Inconel fasteners more expensive than stainless steel?
Yes, Inconel fasteners are significantly more expensive due to their high nickel content and superior mechanical and corrosion properties.
Where can I buy Inconel fasteners in bulk?
Bulk Inconel fasteners are available from industrial suppliers such as Fastenal, Grainger, and international manufacturers based in the USA, Germany, and India.
What is the shelf life of Inconel fasteners?
Inconel fasteners have no specific shelf life and can last for decades if stored in a dry, corrosion-free environment.
