Is this potential order really useful in other aqueous solutions?
Yes, the galvanic series of stainless steels in flowing sea water may be used as a guide in predicting galvanic relationships in other aqueous solutions. The paper as presented is an abbreviated version of the paper as prepared. The paper reports that while the potential values may change with different electrolytes under different conditions as to aeration, flow, temperature, corrosion, etc., the relation of one alloy to another in any one electrolyte should follow this pattern. It should be realized that some conditions will exist where the maximum or minimum potential values will control. Under these conditions galvanic corrosion will be either accelerated or retarded to a greater degree.
The author has referred to the increased susceptibility to corrosion by fluorine exhibited by Type 347 stainless steel, which is presumably due to the formation of a volatile columbium fluoride. In...
