This study was carried out to evaluate the effect of microorganisms on the corrosion behavior of carbon steel when exposed to mechanical axial stress. Open Circuit Potential (OCP) and Electrochemical Frequency Modulation (EFM) response were measured on the tensile specimens while applying a constant load in various environments inoculated with different sulfidogenic or iron reducing microorganisms. The fractographic analysis revealed a noticeable impact of the enriched environments on the topography of tensile specimens; however, after the tests were carried out, it was not possible to detect any indications of a Stress Corrosion Cracking (SCC) failure mechanism for the tensile specimens.
