dc.descriptionField tests and laboratory examinations and analysis have been performed on series of super austenitic stainless steel tubes, of which the inner surfaces were exposed to flowing sea - water in a specially designed test rig. The region 1around the middle portion of the tubes in the test rig was subjected to elevated temperature in the steam chamber part of the rig . The tubes from the field .test were examined after splitting in the laboratory with the wild M3C Model optical macro-/microscope and the S.E .M. (Scanning Electron Microscopy) . The corrosion deposit and the biofilm were analyzed with the S.E.M. equipped with energy Dispersive x-ray (EDAX) spectrometer, and x-ray Diffraction (XRDJ spectroscopy. This paper reports the observed corrosion~ resistance behavior of the tubes' alloys. · While all the alloys w ere found to be generally corrosion resistance in sea water, except the 316L, depending upon the test conditions, they were all also found to be susceptible to crevice corrosion attack at varying degrees under high steam temperature. The crevice corrosion occurred under the strongly adherent calcareous layers deposited in the steam chamber portion of the tubes as observed in one of the runs
