Wide Size Range in ASTM B637 Duplex 2205 Flange Bolts, Duplex S31803 2205 Heavy Hex Head Bolts, Duplex 2205 Plow Bolts and Duplex 2205 Nuts.

Duplex Fastener are a combination of Austenite and Ferrite, combining the properties of both. Duplex bolts are also known as DIN 1.4462. In comparison to 316 stainless steel fasteners these Duplex Stainless Steel Fasteners have higher corrosion resistance. The mechanical properties of Duplex 2205 Bolts are almost double compared to SS 316 Bolts.  Duplex Fasteners such as Duplex Steel Bolts, Duplex Nuts, Duplex Screws, Duplex Washers and Duplex Studs are mostly used in oil and gas exploration and marine environments.because of its high resistance to stress corrosion cracking. These Duplex Steel ASTM A479 UNS S32205 Fasteners also perform better in sea water due of good resistance. These fasteners are also suitable to use in Food processing, Pulp and Paper manufacturing & Biofuel production.

Duplex stainless steel fasteners have less nickel and molybdenum contents than their austenitic counterparts of similar corrosion resistance. So because of the lower alloying content, duplex stainless steel bolts, screws or studs can be offered in lower cost. Siddhagiri Metals & Tubes is manufacturing wide variety of ASTM A182 gr. F60 duplex steel fasteners since 1999 in many grades such as ASME B18.2.4.6M nuts, threaded rod/bar, studs, double end studs, tap end studs DIN 976, DIN 975, DIN 2510, DIN 939, DIN 940, DIN 938 studbolts, 12 point nuts DIN 934, ISO 4033, ISO 4032, DIN 935, DIN 936, ASME B18.2.2.
