Duplex steel fasteners offers superiority over standard stainless steel fasteners. We produce duplex stainless steel fasteners in varitie sof bolts, screws, stud bolts, studs, threaded rods, nuts, washers, dowel pins & customised as per drawing. We manufacture fasteners in duplex stainless steel alloys 2205, 2304, S31803, s32205, S32304 & their equivalent grade designation Uranus 45n, DIN EN 1.4462, etc. Duplex Steel Fasteners are mostly hot forged fasteners and key specification includes ASTM A1082. However duplex fasteners are exclusively hot forged under ASTM A182 forging specifications. Duplex 2205 Fasteners are widely used among duplex steel fasteners. Duplex steel fasteners have high strength and moderate to high corrosion resistance in comparison to stainless steel 304/316 & 317.
Duplex Steel is a dual phase stainless steel with equal composition of ferritic and austenitic phase. Owing to which duplex steel exhibits combined properties of regular 300 series austenitic stainless steel and 400 series ferritic steel. Duplex stainless steel has grown popularity in recent years with combined property and lower cost as compared to its precursor parent steel category. Duplex Steel has tremendous potential in fastener industry. Duplex 2205 is currently the most prominent grade among all other duplex grades to be used for fastener manufacturing.
