Is this stainless?
Yes. I'm pretty sure it's 316. These fitting were made by Garhauer. They had just outlived their usefulness.
But this is another reason why I like the welded t-bolts or the threaded eyes and pressed pins.
Ok, question. If I have some surface rust on the standing rigging wires right where they enter the swage terminals - is that something to worry about? The whole setup is not quite a year old, and this rust makes me wonder.
Surface corrosion is a never ending battle. It's a good idea to keep your stainless clean and rust free.
People often ask me what to apply in order to stop the rust. I usually tell them that anything is better than nothing.
I wouldn't have a problem spraying WD 40 on the wire but you have to do it pretty often. Anything that will leave a coat of oil on the stainless is going to go a long way in preventing rust.
It's also a good idea in my opinion to melt some bees wax into the wire above the lower terminal. Mechanical or swage. This will prevent water intrusion. However, this should be done when the piece is new. You don't want to trap moisture and salt inside the fitting.
Some others will tell you that the wax will prevent the fitting from breathing. I have tried it and tested it and I believe it helps.
That said, if your rigging is only a year old, I doubt that you have a problem.

Inspection. Inspection. Inspection. When your boat and it's systems reach a certain age, and that depends on the climate, you have to either inspect things on a very regular basis or just or replace them.
Also, your photo shows clearly that there was leaking around the u-bolts.
If you see any bleeding below around the chainplates, u-bolts or anything else for that matter, it means that there is water getting in somewhere.
Where there's smoke there's fire. Where there's rust, there is corrosion.
If there is moisture around a bolt or chainplate where it passes through the deck, it's a ticking time bomb. You can't see it and the moisture doesn't evaporate.
Just like the tape on the end of the spreaders it keeps the moisture in and the air out.
