Re: Embedded Chain plate maint/replacement
yeah thanks they did not have 316 at the time...the originals where specd to be 304 they have no noticeable pull tp them...so thats what we went with...they are highly polished anyways and I will be pulling them periodically...
the 316 failed cause fo crevice corrosion and cyclic loading...also where it was hidden, also 316 is slightlymore brittle and will crack suddenly whereas apparently 304 will stretch a bit more and give signs of failure something I see good on a chain plate that gets a lot of vibration if SAILED hard...
again Im eager to see what you end up doing...good luck!
ps. those pics are of the old chainplate? mine were really corroded and brown inside...not shiny at all like yours(the pic)
