I think that Aquamet might be a form of 316, but I don't know of it's
work properties. (It might have been a propeller shaft of something
similar). But smoothing it up will be all I need to do anyway.

Aquamet is a family of proprietary alloys made by Armco, not a single
material. The most common, Aquamet 22, makes machining 316 SS seem fun
by comparison. Back when I was working with the stuff I had a huge
turret lathe available to turn it, which made the job bearable, but
not enjoyable. It's incredibly tough which makes it prone to making
extremely long, tough chips.

Nasty stuff. It is sort of a supercharged 316, but the high manganese
content (4 - 6%), combined with higher chromium and nickel, makes it a
bugger to machine.

Not all Aquamet is austenitic. You have to be sure of which grade you're
talking about.
