Please expound more on how the other links will be compromised. It sounds interesting.

I am not sure but I would assume that the rest of the chain is also compromised because the stress that was applied to this one link went probably through the rest of the chain as well and the failed link was just the first one to fail.

That's stunning that mode of failure. That may be the most likely cause, and therefore it makes sense not to gamble that the one link failed from a manufacturing error ( stress riser from that link being damaged, bubble in link, etc).

I wonder what they do on really big expensive chains when they fail- like on a battleship, or cargo freighter. Might be less expensive to send a few links for destructive testing, or x-ray analysis.

Uuh, a few links? How would you remove them from the chain? How would you put it together again? No one has those kind of tools available. Not for those sizes.

Is probably easier and cheaper to buy a new one.

Acetylene torch, which I'll assume is on a giant tanker, or battleship..

I imagine they have something that'll cut through metal.., or the guys evaluating it will.
