In this paper, the corrosion behavior of Q235 steel by iron bacteria in the sedimentary water was studied by using static hanging piece method, and the corrosion characteristic was also studied by using potentiodynamic polarization curve technique and hysteresis loop methods. The results showed that, the corrosion current density of Q235 steel in iron bacteria was higher than in the sterile medium, and the corrosion potential moved negatively; Iron bacteria reduced the corrosion resistance of steel Q235; Anodic polarization curves of Q235 steel in iron bacteria didn’t showed passivation characteristic, and the cathodic polarization curves had obvious hydrogen depolarization characteristic; The presence of iron bacteria could accelerate the the pitting corrosion of Q235 steel.
