Influence of water content on corrosion of iron and stainless steels in organic solvents

Abstract The anodic behaviour of Armco iron, a low alloy steel, and AISI 304L and 446 stainless steels has been evaluated in methanol, dimethylformamide, and acetonitrile as a function of water and aggressive ion content. The observed differences in behaviour in the various environments can be explained by the differing solvating ability of the three solvents.
