When Stainless Steel
Is No Longer Enough
AODSON manufactures custom nickel alloy fasteners for applications where conventional stainless steel may not provide sufficient corrosion resistance, temperature stability or long-term reliability.
Every Fastener Works…
Until It Doesn’t.
Many bolts look identical at room temperature. In real service, chlorides attack, heat accelerates oxidation, acids destroy ordinary stainless steel, and pressure cycling can turn a small material mismatch into expensive downtime.
Choose The Alloy By The Environment
The right fastener grade starts with the medium, temperature, chloride exposure, required strength and inspection requirements. AODSON helps buyers move from environment to alloy choice before production begins.
From Stainless Steel To Nickel Alloy
A premium fastener page should feel like an engineering handbook. Each alloy below represents a different service condition, not a catalog checkbox.
304 / 316L Stainless Steel
Reliable and economical grades for general industrial environments, food processing, marine-adjacent hardware and equipment where corrosion exposure is moderate.
2205 / 2507 Duplex Stainless
Higher strength with excellent chloride corrosion resistance for offshore systems, pump components, chemical plants and seawater equipment.
Alloy 926
UNS N08926 / EN 1.4529
Alloy 926 is a high-performance austenitic stainless alloy designed for extremely aggressive chloride environments where conventional stainless steels may not provide sufficient corrosion resistance.
Inconel 600 / 625 / 718
Nickel chromium alloys for oxidation resistance, corrosion resistance and high mechanical strength in thermal processing, offshore, oil and gas and turbine-related service.
Monel 400 / Hastelloy C276 / A286
Special alloy choices for seawater corrosion, aggressive chemical media, acid processing equipment, high-strength bolting and critical project requirements.
Where These Fasteners Work
Nickel alloy fasteners are selected where the surrounding system is expensive, the medium is harsh, and failure is not a maintenance inconvenience.
Petrochemical Plants
Bolting for corrosive process environments, pressure equipment and project-based maintenance.
High Temperature Systems
Thermal processing, furnace equipment and oxidation-prone service.
Pump & Valve Equipment
Fasteners and components used around seawater, acids and process media.
Marine & Offshore
Long-term resistance for seawater exposure, desalination plants and offshore equipment.
Custom Bolting, Not Commodity Screws
AODSON supports drawing-based and project-based fastener production, including special alloy sourcing, small batch production, inspection and export communication.
More Than A Fastener Supplier
Special alloy fasteners often require review before purchase. AODSON helps customers compare grades, confirm drawings, align inspection requirements and prepare export-ready documentation.
Questions Engineers Ask First
When should stainless steel be upgraded to nickel alloy?
When service includes aggressive chlorides, strong acids, high temperature, seawater exposure, stress corrosion risk or critical reliability requirements, nickel alloy or duplex grades may be a better fit.
Can AODSON manufacture fasteners from drawings?
Yes. AODSON supports drawing-based fasteners, special dimensions, project batches and custom material requirements.
Which alloys are available?
Common options include Alloy 926, Inconel 600, Inconel 625, Inconel 718, Monel 400, Hastelloy C276, A286, 2205 duplex and 2507 super duplex.
What information helps with quoting?
Send drawings, alloy grade, standard, quantity, working temperature, service medium, surface finish and inspection or certificate requirements.
Built For Environments Where Failure Is Expensive
Send your drawings, specifications, working temperature, medium and quantity requirements. AODSON will help review the material, fastener type and manufacturing route for your project.
