Corrosive mediumis a little known phenomenon and it is necessary to emphasize that corrosion is a secondary epiphenomenon in the development of bacteria and their metabolism, or that the occurrence and development of bacteria are accidents at the surface of the corroded parts. The purpose of this research is to determine the mechanical properties of a sheet steel (type FeP-05-MB) submitted to corrosive mediums. These mediums are: ambient, saline and microbiological. After the action of these mediums, the metallic samples were analyzed in order to observe the resistance at corrosion after their corrosion by different mediums.
