Corrosion product: at high temperature magnetite corrosion products it will coat the iron/steel to prevent oxygen to reach underlying metal. Mostly, at low temperature lepidocrocite formed and with time it transformed into most stable goethite. Akaganeite formed in marine environments
Corrosion products: pyrophoric iron sulfide (pyrrhotite-FeS) results from the corrosive action of sulfur or sulfur compounds (H2S) on the iron (steel) and moisture
