AODSON 2507 duplex stainless steel full thread hex bolts in UNS S32750 for marine, offshore, desalination and chemical processing fastening applications.

2507 duplex stainless steel hex head plugs are compact threaded sealing parts designed for closing ports, threaded holes, hydraulic blocks, pump bodies, valve components, and pipe fittings that work in corrosive environments. Compared with common 304 or 316 stainless steel plugs, 2507 duplex stainless steel offers higher strength and better resistance to chloride attack, making it a practical choice for marine, chemical, desalination, offshore, and high-corrosion industrial equipment. Product Overview AODSON manufactures 2507 duplex stainless steel hex head plugs with a clean machined finish, accurate external threads, a flat sealing end, and a hexagonal head for wrench tightening. The external hex design gives installers firm tool engagement, while the short threaded body allows the plug to seal threaded ports where space is limited. The plugs can be supplied according to customer drawings, samples, or thread standards. Common options include metric thread, BSP, NPT, UN/UNC/UNF, customized shoulder dimensions, chamfered edges, passivation, marking, and different surface finishes. Why Choose 2507 Duplex Stainless Steel? 2507 duplex stainless steel, also known as UNS S32750, combines high chromium, molybdenum, and nitrogen content with a duplex austenite-ferrite microstructure. This gives the material a strong balance of mechanical strength and corrosion resistance. For threaded plugs, this matters because the part often sits in contact with seawater, chloride-containing liquid, chemical media, or outdoor industrial atmospheres for long service periods. Key Features Typical Applications 2507 duplex stainless steel hex head plugs are used in equipment where a reliable threaded closure is required and ordinary stainless steel may not provide enough corrosion protection. Typical applications include marine hardware, desalination systems, pumps, valves, pressure equipment, chemical processing lines, offshore platforms, heat exchangers, hydraulic manifolds, and custom stainless steel assemblies. Manufacturing and Quality Control AODSON focuses on stable machining and practical inspection for industrial fasteners. During production, attention is given to thread…

Duplex Stainless Steel 2507 Double End Stud Bolts for Corrosive Service AODSON duplex stainless steel 2507 double end stud bolts are manufactured for assemblies that need strong threaded fastening performance in chloride-rich and aggressive environments. The material is a super duplex stainless steel grade with a balanced austenite-ferrite structure, giving the fastener high mechanical strength and excellent resistance to pitting, crevice corrosion, and stress corrosion cracking. Each stud bolt is machined with threaded sections at both ends and a smooth central shank for clear identification and stable installation. The marking AODSON 2507 can be applied to the unthreaded body for traceability, while thread size, length, pitch, end style, and surface finish can be produced according to project drawings or common industrial specifications. Why Choose 2507 Duplex Stainless Steel? 2507 duplex stainless steel is widely selected for marine engineering, chemical processing, offshore equipment, desalination systems, pump and valve assemblies, and other applications where standard 304 or 316 stainless steel may not provide enough corrosion resistance. Its higher chromium, molybdenum, and nitrogen content helps improve chloride resistance, while the duplex microstructure supports higher yield strength than many austenitic stainless steels. Product Features Material: Duplex stainless steel 2507 / UNS S32750 Product type: Double end stud bolt / double threaded stud Available standards: ASTM, DIN, ISO, ASME, or customer drawing Thread options: Metric, UNC, UNF, and customized thread forms Finish options: Machined, polished, passivated, or customized surface treatment Suitable for high-strength fastening in corrosive and chloride-bearing environments Typical Applications These 2507 double end studs are suitable for flange connections, valve bodies, pressure equipment, heat exchangers, offshore structures, pipeline systems, and pump assemblies. They are especially useful where the fastener must resist corrosion while maintaining reliable clamping force over long service periods.
