I'm trying to specify stainless steel bars (3/4" or 1" diameter, hex or square x 18" long) to be used in an abrasive environment as a survey monument. They will need to be welded and very hard to resist erosion. I'm looking at cost, availability and workability. Specifically 303, 304 and 316. Which would be the best?

No 300 series SS will handle this level of abrasion, UNLESS you can find cold drawn bar. I have seen 3/4" bar in 304 drawn to 100kis yield, 150ksi UTS.
I could send you a piece of 304 tubing 1.385" od x 0.200" wall that is made to that strength.
I would suggest that you look at using a sacrificial cap that could be replaced. Long term flow will damage any material.
