Duplex 2304 Fasteners

AISI 4130 Bolts

Duplex Steel Fasteners a.k.a Duplex Stainless Steel Fasteners are main product line for BoltPort Fasteners. This includes manufacturing and supply of duplex 2304 fasteners such as bolts, screws, stud bolts, threaded rods, nuts, washers, dowel pins, and other custom bolting components. We offer both metric and imperial sized fasteners in duplex alloy 2304. Duplex stainless steel 2304 fasteners are produced from premium quality rolled bar stock or forged bars with latest material specifications. Boltport can manufacture alloy 2304 fasteners in ASME, DIN, ISO & other international dimension standards. These duplex fasteners are also available in equivalent grades F68, UNS S32304, DIN EN Werkstoff 1.4362.

Hex bolts, heavy hex bolts, stud bolts, tap end studs, double end studs, threaded rods, hex nuts, heavy hex nuts, nylock nuts, hex jam nuts, castle nuts, plain washers, spring lock washers and tab washers, dowel pins are most common of duplex alloy 2304 fastening parts.

About Duplex 2304

Duplex 2304 is stainless steel duplex alloy grade with balanced structure of ferritic and austenitic stainless steel. Duplex 2304 has high strength, toughness and resistance to stress corrosion cracking, high thermal conductivity and low thermal expansion with ease of fabrication. However this alloy 2304 should not be used for application in enviroment exceesing 250-325 degree celcius for prolonged period of operation.
