Corrosion behaviour of stainless steel in seawater

The effect of temperature and concentration of sulphide ions on the corrosion behaviour of 304L and 316L stainless steels in seawater has been investigated by different electrochemical methods. Open circuit potential measurements, linear and potentiodynamic polarization methods have been employed during the investigation. It has been found that the corrosion rate increases with the seawater’s increasing temperature and the concentration of sulphide ions. Surface analysis with a light microscope and optical profilometer after potentiodynamic polarization measurements reveal that the number and depth of pits also increase in the same way.
