Corrosion of structural steel - SteelConstruction.info

The corrosion of structural steel is an electrochemical process that requires the simultaneous presence of moisture and oxygen. Essentially, the iron in the steel is oxidised to produce rust, which occupies approximately six times the volume of the original material. The rate at which the corrosion process progresses depends on a number of factors, but principally the 'micro-climate' immediately surrounding the structuSee more on steelconstruction.infoCorrosion of Carbon Steel in Marine Environments: Role corrosion and materials degradation Review Corrosion of Carbon Steel in Marine Environments: Role of the Corrosion Product Layer Philippe Refait 1,*, Anne-Marie Grolleau 2, Marc Jeannin 1, Celine Rémazeilles 1 and René Sabot 1 1 Laboratoire des Sciences de lIngénieur pour lEnvironnement (LaSIE), UMR 7356 CNRS-La Rochelle Université, Av.
