Abrasion resistant. It's used for cutting edges for heavy equipment and farm implements as well as bed surfaces for dump trucks. Does a nice job of holding up, but it will still not perform like armor plate.
I have shot steel armor plate in the army. I have also gone to ranges that claim to have Armor plate targets and had jacket returns from ranges that put up simple steel and the pock marks send ricochets back to the firing line.
My safety and those around me are worth knowing more than someones word. I just want to leave the range with the same number of holes that I went with.
AR500 steel is through hardened. Please take a look at the links posted below. And while it is not "Armor plate" it is commonly used for targets and back stops.
If you had a bad batch or AR500 from another vendor I am sorry. I assure all of you that this is AR500 plate and will stand up to the rounds listed above. You are all welcome to stop over and see my personal target if you would like. It is sitting just shy of 1000 rounds including 223, 22-250, 243, 9mm, 44mag and 45acp.
Ricoshets may and likely will happen when shooting steel targets. Eye protection is an absolute must. I think all of you that participate in the MNGT steel shoots will agree that it is fun and safe.

"Built in strength and through hardness gives AR500 exceptional resistance to both
impact and sliding abrasion. Hardness of material increases in the center."

AR 500 steel plates are premium abrasion-resistant heat treated plates exhibiting through-hardening, improved forming and welding capabilities.
