VERSATILITY OF SUPERAUSTENITIC STAINLESS-STEELS IN MARINE APPLICATIONS

Corrosion of construction materials in marine applications is a major problem. The frequent variations in chloride ion concentration and tem perature experienced by a system pose a serious threat. This investiga tion evaluated the performance of superaustenitic stainless steels in marine applications by potentiodynamic anodic polarization studies. Th e concentrations of metal ions such as iron, chromium, and nickel at d ifferent impressed potentials were analyzed by inductively coupled pla sma spectrometry, which revealed little tendency for leaching of metal ions.
