Galvanic corrosion between Inconel 625 and Super duplex
Galvanic corrosion between Inconel 625 and Super duplex
(OP)
Hello! Are there anyone som have some documented experience or relieable sources, good or bad, with electrical connection between 25% Cr super duplex and Inconel 625? Offcourse they have different galvanic potential, but enough to cause severe corrosion problems? The system is in sea water, with no cathodic protection. Design life typical 20 years.

Now crevice corrosion may be another mater. It would not surprise me if the 625 was the first to go.
