AR 500 is 500 Brinell. I am not sure what that works out to in Rockwell C, but I am sure you could find a chart if you looked. AR stands for Abrasion Resistant.

A lot of light armor on support equipment is AR400 or AR380. Even lead or copper going fast enough will penetrate armor plate. Hardness helps, but velocity is the armor killer.

You could find it's relative hardness by what scratches it, vs what it scratches. Common 440 C knives are usually around 55 HRC Higher quality knives may be around 60.

You can also check them against files. If you use a normal nicholson bastard file you'll have a pretty good idea just by feel about how hard the object you are filing is.
