Abstract:

The report presents the results of exposing specimens of AISI type 316 stainless steel, provided with standard crevices, and galvanically coupled with various other metals, in sea water. The exposure lasted 115 days. Complete protection against all forms of corrosion including crevice corrosion was afforded the 316 steel by coupling with most of the metals, including the standard aluminum-base and zinc-base galvanic anodes. No evaluation of the effectiveness of magnesium alloys could be made because the anode was completely expended before termination of the experiment. AISI type 316 L was observed to crevice-corrode when coupled to the regular 316, and in that instance the 316 did not crevice-corrode. Author
