Abstract

Abstract

The physico-chemical behavior of rare earth elements in low sulphur 16Mn steel and their ability to enhance the corrosion resistance of the steel in sea water studied in this paper. The results indicate that Ce and La in 16Mn steel all have the abilities such as deoxidation, desulphidation, refining grains and cleaning grain boundaries and matrix etc. The anodic and cathodic polarization curves show that the rare earth elements added in 16Mn steel enhance the corrosion resistance of the steel in sea water.
