2205 DUPLEX FLANGES

Ace Alloys LLP offers premium 2205 duplex stainless steel flanges (UNS S32205 / S31803), engineered for superior corrosion resistance and strength in demanding industries. This duplex grade combines austenitic and ferritic microstructures, delivering twice the yield strength of 304 stainless steel (around 450 MPa minimum) while resisting stress corrosion cracking, pitting, and chloride attack—ideal for oil & gas, chemical processing, desalination, and marine applications.

Available in weld neck, slip-on, blind, socket weld, and orifice types per ASTM A182 F51/F60 and ASME B16.5 standards. Sizes range from 1/2" to 48" NB, with pressure classes 150# to 2500#, PN6 to PN64, and face types like RF, FF, or RTJ. Chemical composition includes 21-23% Cr, 4.5-6.5% Ni, and ?0.03% C for optimal weldability and heat resistance up to 300°C.

These flanges excel in high-pressure pipelines, offshore platforms, and sour service environments, offering fatigue resistance and longevity that cut maintenance costs. Ace Alloys LLP, based in Kaly?n, Maharashtra, ensures ISO 9001:2015 certification, custom dimensions, and competitive pricing with global delivery.
