This test is performed by AASHTO T96 or ASTM C131: for resistance to small size coarse aggregation by abrasion and impact in a Los Angeles machine. Los Angeles's abrasion test on aggregates is a measure of aggregate toughness and abrasion resistance such as crushing, corrosion and disintegration.
What Makes Steel Abrasion Resistant? AR steel alloys are made from billets of steel containing different alloying elements such as carbon, manganese, chrome, nickel, and boron. Of all these alloys, carbon is the most important in making steel abrasion resistant, as it increases hardness and toughness.

abrasion of commercial grinding balls. Most commercial balls are made of steel with a carbon content of about 0.5 to 1.0 wt % and heat treated to maximize resistance to abrasion, fracture, and spalling. Fully hardened balls have a tendency to fracture and spall. The odd shaped "balls" found inside ball mills are a result of fracture and
Many abrasion-resistant steels are based on a quenched and tempered martensitic microstructure, because the hardness of the steel should intuitively matter in determining the wear rate.
