Hi Thomas,

There was a reason I said cromox chain. There are many, many different qualities of SS. If you are at anchor for extended period of time some of those will suffer crevice corrosion because of oxygen deprivation. Cromox is resistant to this .... at a price.
Crevice corrosion will be barely noticeable until it breaks, not the nicest way find out.

Cheers,
