AODSON 2507 duplex stainless steel full thread hex bolts are engineered for bolted connections where high strength and dependable chloride corrosion resistance are both essential. Manufactured from super duplex stainless steel grade 2507 (UNS S32750), these external hex head fasteners are a practical option for marine, offshore, desalination and chemical processing assemblies.
2507 Super Duplex Stainless Steel for Severe Service
Grade 2507 has a balanced duplex microstructure and elevated chromium, molybdenum and nitrogen alloying. This material combination is chosen for strong resistance to pitting, crevice corrosion and chloride stress corrosion cracking. In equipment exposed to seawater, brine or chloride-bearing process media, 2507 fasteners can provide a more robust material selection than commonly used austenitic stainless grades, subject to the project design specification.
Product Features
- Material: 2507 super duplex stainless steel / UNS S32750
- Fastener type: External hex head bolt with full thread
- Finish: Clean machined stainless surface; head marking available as specified
- Dimensions: Metric or inch sizes, thread pitches and lengths supplied to order requirements
- Standards: Dimensional and testing requirements can be confirmed according to the applicable DIN, ISO or ASTM project specification
- Matching items: Compatible 2507 nuts and washers available for material-consistent assemblies
Typical Applications
2507 duplex stainless steel fully threaded hex bolts are suited to fastening assemblies exposed to saltwater spray, seawater handling, high-chloride liquids and demanding industrial atmospheres. Typical installations include offshore structures, marine equipment, desalination plants, pumps and valves, heat exchangers, chemical processing systems, pulp and paper facilities, and coastal infrastructure.
Full Thread External Hex Design
The fully threaded shank provides thread engagement along the available bolt length, helping accommodate flange joints, mounting arrangements and equipment assemblies requiring flexible clamping positions. The conventional external hex head supports secure wrench engagement and controlled tightening with standard tooling.
