I think it must depend to a large extent on the 
alloys used, the installation and proper/improper 
contact with other metals, and the quality of the 
SS. I have SS rigging on my boat, now 36 years 
old, no troubles. I was at one time an NDT 
inspector and have done dye checks on it before, 
no troubles but of course that by itself is not a 
clean bill of health.

Titanium is a very funny metal. When I raced 
bikes, I got ti spokes when they first came out. 
They would last during a very tough fast race, 
then while cooling down going slow, suddenly PING! 
Later I guess they changed the alloy because that 
became much less of a problem, but ti is notorious 
for 'notch fatigue'. I don't think I would trust 
it for that application. Galling of turnbuckles 
would also be a problem as ti galls easily.-Ken
