I've seen SS "rusted" were there's been a layer of something else like coffee on a teaspoon I found washed up on the beach. Wire, where it is tightly woven would be a prime candidate. Flexing might be all that's needed to either cure or cause the problem. There can be problems where SS has been welded. Have a look at the pulpits of yachts in the marina next time you are paddling past. SS is the best but not perfect. Rudder lines - I always use 2mm Spectra, if it does break you can tie a knot in it.
