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.
