Abstract
In order to appraise the influence of s-phase on the behaviour of duplex stainless steels, two tests are performed. The first one is the double loop electrochemical potentiodynamic reactivation (DLEPR) test that indicates the degree of sensitisation to intergranular corrosion. The second one is the slow strain rate test (SSRT) that enables us to relate the degree of sensitisation to stress corrosion cracking. A metallurgical study is also performed on two duplex stainless steels of grade UNS S31803. Sensitisation is carried out by several heat treatments at 675°C or 900°C. The influence of s-phase is clearly shown on the mechanical properties and the corrosion resistance.
