Abstract
Pitting and crevice corrosion susceptibility of some super austenitic stainless steels in- sea water were determine element to improve the resistance to pitting determined by field tests and laboratory examinations · (5 6 7) and analysis. This paper reports the observed corrosion and crevice corrosion . Streicher (l 0) has also susceptibility behaviour of the tubes' alloys. The inner observed that the combined addition of molybdenum, surfaces of the steel tubes were expo$ed to flowing sea nitrogen and silicon provided effective corrosion water a specially designed tests rig. The steam c:b.amber resistance behaviour to type 3 I 6 stainless steels. part of the rig which was subjected to elevated temperature was the region where the middle portion of ·the tubes were located. After splitting in the laboratory, the tubes from the field test were examined with optical macro-/microscope (Wild M3C Model) and the scanning electron microscopy (S. E. M.). Analysis of the corrosion deposit was performed with the S. E. M. equipped with Energy Dispersive X -ray (EDAX) spectrometer, and the X -ray Diffraction spectroscopy (XRD)_. Thoz1e.h all !!:~~!Joys, except the 3161., were found to be generally corrosion resistant substantial · .... .. . . . - ' ' 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
