AbstractAbstract
[en] Twenty-two ≅ 25%Cr α-γ duplex phase stainless steels are suitable for CO/sub 2/-brine system. The pitting resistance in the ferric chloride test at 300C is improved by means of regulating alloying elements both in a pitting index and a fraction of austenite phase. Concerning the duplex stainless steel, it is preferable to include the term of nitrogen content in the expression of pitting index, e.g. P.I. = Cr + 3Mo + 16N. By the newly developed welding materials, the pitting resistance of welds could be improved. Influence of H/sub 2/S and O/sub 2/ contamination on CO/sub 2/ corrosion of duplex stainless steels are discussed
