There are scarce references in the literature on the corrosion behavior of duplex stainless steels in marine media containing sulfate reducing bacteria (SRB) like those encountered in off shore oil extraction.

The differences between abiotic (plain 0.6 M NaCl solution) and biotic conditions (SRB cultures) on the corrosion resistance of duplex stainless steel SAF 2205 is studied in this paper by using laboratory electrochemical experiments.

Results show that the resistance of SAF 2205 duplex steel to pitting is markedly affected by the presence of SRB in the medium.
