Fiberglass burried chainplate recommended metals
Here is another reference that I found, now showing 254SMO a better solution (based on the report's testing criteria and conclusions) as a potential replacement for 300 series metals. It seems the copper content helped preserve the passive resistance capability in 254SMO as compared to AL6XN...- boatrus

Fiberglass burried chainplate recommended metals
I am finding 'new' use of Nitronic 50 (tm) in the marine industries as chainplate (and historically used as rod rigging) material on new production build sailboats and mega yachts (replacing 300 series metals). But looking at the chemistry, it is not quite up to the 6% Mo: Carbon 0.06 max...- boatrus

Fiberglass burried chainplate recommended metals
I am replacing marine chain-plates on a 28 yo boat that are encapsulated in the hull. The original plates corroded in two places --typical anaerobic SCC-- on questionable 316 SS (unknown chemistry). So my question is, what better metal choices do I have for fiberglass encapsulated metals in a...- boatrus
