I think you're right on the 'eye' thing, have seen that too, and
sometimes on other materials.

I've spec'd a couple items I've sourced out here in 303 for easier
machining. Nobody seems to know what it is in rural AU. Everyone out
here uses 304 or 316 in the abattoir industry.

303 would not be a good choice in the abattoir. It is not nearly as
corrosion resistant as 304 or 316. And shouldn't be welded either.
