The Use of Duplex Stainless Steel in Bridge Structures

Duplex stainless steels have many desirable characteristics which can be exploited in bridge structures. They are particularly suitable wherever certain environmental conditions combine with the need for high load-bearing capability. The paper discusses the mechanical and physical properties of this family of stainless steels. Guidance is given on grade selection, design using Eurocode 3 and sustainability attributes. Case study information of some recent duplex stainless steel bridges is presented.
