The metallurgical structure consists of two phases, austenite and ferrite in roughly equal proportions and hence these steels are called duplex steels.
Duplex stainless steels are about twice as strong, have significantly better toughness and ductility as compared to regular ferritic stainless steels. They show very good stress corrosion cracking (SCC) resistance. When considering Duplex stainless steel for heat Exchangers, typically there is even more benefit. The lower nickel content of the Duplex grades means that a better thermal conductivity as compared to the austenitic equivalent grade.
