rust, but they do have four .5" holes around the perimeter and a
.5"x.5" milled rabbet on two sides. (I'm sure in metalworking they
wouldn't be called a rabbet, would they?)

Probably "shoulders".


I'm using two of the plates for a welding table top, but I was going to
sell the others.

Careful with heating the plates. If you get them red (even in just a
localized spot), they'll probably harden and you could get a chip in your
body if you subject it to shock (with a hammer, for instance).
