The wear resistance of the material not only depends on the hardness, the more important is  the ratio of material hardness Hm and grains hardness Ha. When the Hm/Ha ratio exceeds a certain value, the wear volume will be decreased rapidly.

>>When Hm/Ha is less than or equal to 0.5-0.8, it is hard abrasive wear, the wear resistance will not be increased when we try to improve hardness.
>>When Hm/Ha is greater than 0.5-0.8, it is soft abrasive wear, the wear resistance can be increased when we try to improve hardness.

Wear resistant metal materials are usually means wear resistant steel plate, but this kind of steel has not become a fully independent steel grade, high manganese steel is the mostly recognized wear resistant steel.

chromium carbide overlay plate is also a typical wear resistant steel plate which is widely used in cement and mining industry, it is bimetallic composite wear plate and welded by chromium carbide overlay on a mild steel base plate.
