摘要：

The relative superiority of duplex stainless steels (DSS) over austenitic grades with regards to stress corrosion cracking (SCC) is discussed. The benefits of nitrogen to SCC resistance of DSS are provided. The selective dissolution of phases and its impact on corrosion SCC is reviewed. The hydrogen embrittlement of DSS is reviewed with emphasis on the ferrite participation, the role of environments and fracture morphology. The evolution of secondary phases and precipitates and the resultant change in corrosion resistance and SCC in DSS is discussed.
