Who has AR500 Plate?

Most practical way to check if it's AR500 is to try and mark it with a hand file. If it's real, it should be very very hard to mark up, since the hardness should be only a little less than hardened tool steel. This is the same principle as testing vs. mild steel with a punch, but will ballpark you a more accurate figure.
You can also compare sparks from an angle or bench grinder but imo that's sort of a fool's errand. If you do, the sparks should be more effervescent than mild steel, but travel a shorter distance- that's for austenitic manganese steel out of my welding textbook. I've never touched AR500 with a grinder myself so take that info for what it's worth- I'd stick to testing with a hand file.

I can get my hand on some cut offs of Mil-A-12560 and Mil-A-46100. It does come at a higher cost but this is the stuff that armored vehicles are made of. It is hard as hell. This material when passes is listed as the numbers provided but if the material does not pass a Mil cert it turns in AR 500. We have all Mil certified material.
PM me if interested and that way I can keep you posted.

No one generally carries AR500. I always order it in and I have ordered it for targets from Russel in GP.
