Galvanic corrosion - facts and how to reduce the risk ...
If two stainless steel grades of similar type are galvanically coupled, there is usually no risk of galvanic corrosion. However, if corrosion occurs for some reason in one of the stainless steels, the active steel corrodes with a higher corrosion rate than usual, driven by the difference in potential between the active and passive states.
