Effect of sulfate reducing bacteria on corrosion of stainless steel 1Cr18Ni9Ti in soils containing chloride ions

▶ The effect of SRB on corrosion of the stainless steel was investigated. ▶ The effect of chloride ion on corrosion of the stainless steel was investigated. ▶ Pitting susceptibility of the steel was enhanced by SRB and chloride ion. ▶ Many pitting holes were clearly observed on the surface of the steel.
