The “AR” in AR500 and 550 refers to the heat-treated material’s abrasion-resistant properties. It has a Brinell hardness number of 500, which is much more complicated than mild steel. Targets made from softer materials tend to pit when shot with high-velocity ammunition. Pitting can resul...

AR500, therefore, has a higher Brinell Hardness than AR400. Unlike other steels, where the primary properties taken into consideration are tensile strength or toughness, abrasion resistant steels are graded according to their Brinnell Hardness. Hardness is one of the most...
