Pitting corrosion of a stainless steel is illustrated in the Figure 1. The actual pitting corrosion phenomenon is shown on propeller shaft of high speed craft, and the pit depth was measured with dialMicrobial Corrosion of API 5L X-70 Carbon Steel by ATCC , x70 pipe corrosion pitsVarious cases of accidents involving microbiology influenced corrosion (MIC) were reported by the oil and gas industry. Sulfate reducing bacteria (SRB) have always been linked to MIC mechanisms as one of the major causes of localized corrosion problems. In this study, SRB colonies were isolated from the soil in suspected areas near the natural gas transmission pipeline in Malaysia.
