Theoretical resistivity for stainless steel
WebbIn principle, stainless steels should be in the passive state in soils, but the presence of water and aggressive chemical species such as chloride ions, sulphates and as well as types of bacteria and stray current, can cause localised corrosion. In such aggressive environments, stainless steel piping buried in soils should therefore be coated.
