UNS S32205 Duplex 2205 is a nitrogen-enhanced duplex stainless steel combining the benefits of both austenitic and ferritic microstructures. With approximately twice the yield strength of standard austenitic grades (304/316) and outstanding resistance to chloride stress corrosion cracking (SCC), these seamless tubes are the preferred choice for aggressive heat exchanger service in offshore oil & gas, chemical processing, and seawater-cooled applications.
