Duplex steel products are made from stainless steel with a mixed austenitic-ferritic structure, offering high strength and corrosion resistance.
Common grades include UNS S31803 and S32205 (Duplex 2205).
They are widely used in offshore, oil & gas, marine, and chemical industries.
They provide higher strength, excellent corrosion resistance, and better stress corrosion cracking resistance than standard stainless steel.
Products include bolts, nuts, washers, pipes, flanges, and round bars.
