Increase in the wear resistance of hammer mill hammers ...

1. Additions of vanadium (0.4–0.7%) increase the strength, hardness, and wear resistance of austenitic manganese steel treated to an austenite—carbide structure with dispersed carbides. 2. The wear resistance of hammers manufactured from steel 110G13FL and treated to an austenite —carbide structure is 50% higher than that of hammers manufactured from austenitized steel 110G13L.
