Was informed, when I still was sailing, that a crack in a stainless steel
turnbuckle could grow 1 inch/hour if oxygen deprived, which can happen if it is
covered with sea grass. That means that the turn buckle can snap within minutes
even if it was perfect before it got covered.
I had two heat exchanger for my swimming pool corroded to scrap metal in a few
moths myself due to oxygen deprivation.

Sailors have long known about and been wary of stainless steel corrosion.
Reader's discussion Safety Wire lines may be interested in this brief
article. The primary issue is unless the Stainless Safety line is oxygen,
the oxide layer that protects it is not maintained and corrosion can begin.
This is especially true at wire terminals and where the wire is covered.
Plastic coatings of wire is disallowed on ocean racing boat life lines, as
it can not be inspected. Bare wire is better.
