Are solid stainless steel rods any less vulnerable?
What alloy is used for major standing rigging; there must be some less prone
to chloride/stress attack, or?
I worked with some higher than 316 plus extra titanium alloy(32?) for
seawater boiler; it was a much better choice than regular 316.
I am not sure if this alloy is being offered in steel rope shape.
Any one knows more about it?
thanks

Most sailboat rigging is 304. Some is 316 but it's a bit weaker than
304 (about 10%).

Rod rigging is usually Nitronic 50. More corrosion resistance but no
warning of failure like broken strands. About twice the cost of wire
rope so it's restricted to racing boats
