Corrosion of Mild Steel by Iron Sulphides

Abstract

The corrosiveness of several chemically prepared iron sulphides to mild steel has been studied with regard to the amount of sulphide and the period of exposure of the steel to the sulphide. All sulphides examined were found to be corrosive and there appears to be a link between corrosiveness and the sulphur content of the sulphides. The corrosion mechanism is discussed in the light of the literature.
