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.

Thats because 304 corrodes far less than 303..and 316 hardly corrodes
at all.

As you know...the liquids in the abattoir industry are not simply
"water"..but have a goodly percentage of hydrocloric acid in them.
