DUPLEX STAINLESS STEEL UNS S32205

AF Aanuraj Hot Forged Threaded Nuts and Bolts are duplex (ferritic/austenitic) stainless steel grade. AF Aanuraj Fasteners are used in various applications due to both excellent corrosion resistance and high strength.

AF Aanuraj Duplex S32205 Fasteners gives better guaranteed corrosion resistance. It is not generally suitable for use at temperatures above 300ºC as it suffers from precipitation of brittle micro constituents, nor below -50ºC because of its ductile-to-brittle-transition.

AF Aanuraj DUPLEX Fasteners Applications:

Chemical processing, transport and storage,

Oil and Gas exploration and processing equipments.

Marine and other high chloride environments,

Pulp and paper digesters, liquor tanks and paper machines.

AF Aanuraj DUPLEX Fasteners Corrosion Resisitance.

Our Fasteners has excellent general corrosion resistance; superior to Grade 316 in most environments. Excellent resistance to localized corrosion including intergranular, pitting and crevice corrosion; the CPT of 2205 is generally at least 35ºC. The grade is also resistant to chloride stress corrosion cracking (SCC) at temperatures of up to about 150ºC. Grade 2205 will often perform well in environments which cause premature failure of austenitic grades. It has better resistance to sea water then Grade 316.
