Duplex stainless steels have been actively developed by European companies since 1935. Their properties make them very attractive compared to equivalent austenitic grades. They indeed exhibit higher resistance to stress corrosion cracking higher mechanical properties and lower alloy cost. They are today widely used in many industrial sectors for instance in the oil & gas chemical pulp & paper and water industries. Duplex stainless steels are also relevant candidate materials for architecture building and construction projects especially when considering sustainability and Life Cycle Cost.This paper provides an overview of the main properties of duplex stainless steels in terms of chemical composition mechanical and physical properties. Then the results of an extensive atmospheric field test program are reported confirming that duplex stainless steels can be interesting candidate materials for architecture building and construction projects compared to the ferritic-martensitic grade UNS S41003 and standard austenitic grades S30403 and S31603. Finally successful experiences with duplex grades in structural applications after 10 to 20 years of service will be given.Key words: Duplex Stainless Steels Architecture Building Construction Bridges Atmospheric corrosion Mechanical properties.
