Not arguing that if you immerse it in electrolyte you will have a problem. I’m talking about in “dry” locations. And no location on a boat is truly dry. But in any case, above water line applications.
I’m not sufficiently well versed to argue the matter out. I’m simply reporting what I observe all too often in practical application.
In this particular case I’m supporting the idea that a SS tank in an Aluminum keel is a bad idea.
I’m also reporting I observe corrosion where two materials come close together.
I may be wrong in my approach to a fix. When you say in “certain metals” you cause embrittlement, which metals? And what is the rate of degradation? If it’s 50 years I don’t care as long as it stops or slows rust.
P.S. I just did a quick internet search and it seems that welding 316 to mild steel is a very common practice with no special warnings, including on boats.
