Duplex steel 2205 Flanges
2205 is a Duplex combination of Ferritic & Austenitic. It has higher corrosion resistance than 316 (3% min. Moly vs 2% in 316) Duplex 2205 is highly resistant to stress corrosion & Chloride cracking. Duplex 2205 is cost effective because it has only 5% Nickel. Duplex stainless has high strength, ductility, toughness and weldability.

Duplex steel 2304 Flanges
ASTM A182 F51 is material specification for forged Duplex Stainless Steel Products. This includes forged duplex stainless steel flanges, pipe flanges, forgings, rings, blinds, etc, suitable in corrosion resistant applications. Grade F51 is grade equivalent to Duplex 2205 & UNS S31803.
ASTM A182 F51 Flanges are manufactured from Duplex steel forging stock. These duplex Steel flanges can be forged from direct forging stock, duly tested; followed by heat treatment, machining, visual inspection, dimensional check, final non destructive tests, certification, packing & shipping.
Duplex ASTM A182 F51 Flanges are forged into Weld-Neck, Slip-On, Socket-Weld, Threaded, Blind, Orifice, Long Weld Neck, Weldo, Nipo,Expander, Reducing & Special Nozzle type Flanges.
Duplex 2304 Flanges Specification
Stainless steel grade Duplex 2304 is a duplex stainless steel type with a structure that is a balance of ferritic and austenitic. It has high strength and toughness, resistance to stress corrosion cracking, high thermal conductivity, low thermal expansion, and easy fabrication. It is recommended that this steel is not used in areas where the steel would be exposes to temperatures over 1058°C (570°F) for prolonged periods.
