Oct 10, 2018 · This corrosion can occur when connecting stainless steel to aluminum, carbon steel or other types of metals and it is one of the most common and destructive forms of corrosion. When galvanic corrosion occurs, it is due to the difference in electrode potential because one of the metals becomes the anode and the other the cathode.Microbiologically Influenced Corrosion of Stainless heat exchangers, corrosion Summary: Case histories from experience and the published literature illustrate factors which resulted in microbiologically influenced corrosion (MIC) of stainless steel piping, storage tanks and heat exchangers by waters used for hydrotesting, cooling and other purposes.Fundamentals of Metallic Corrosion in Fresh Waterstainless steel, for example, the initial current is about the same, but after a few hours the galvanic current from the stainless is only a small fraction of that from copper. Thus a stainless steel screen connected to a mild steel casing would cause far less corrosion on the mild steel than would a bronze or Monel screen.
