Super Duplex 2507 Stud Bolts
UNS S32750 · ASTM A182 F53 · EN 10204 3.1 / 3.2

Super Duplex 2507 is one of the most specified alloys in offshore and subsea bolting. Its dual austenitic-ferritic microstructure gives it roughly twice the strength of standard austenitic stainless steel, combined with excellent resistance to chloride stress corrosion and pitting — properties that matter in seawater-exposed flanges, subsea manifolds, and topside pipework on offshore platforms.

We supply Super Duplex 2507 stud bolts to ASTM A182 F53 and ASTM A193 in standard flange bolt lengths and custom project lengths. Available in double-end and tap-end configurations. Sizes from M10 to M64. Full EN 10204 3.1 documentation supplied. PREN value above 40 confirmed on all stock.
