When quoting a Brinell hardness number, abbreviated to BHN or HB, the load number must be specified as well as the material the ball was made of. For example, HBS 20/3000 would mean that a hardened steel ball indenter was used. The 20 is the ball's diameter in millimeters, and the 3000 is the force in kilograms.

White Iron Ball Mill Liner distinctive features is that the M7C3 type eutectic carbide micro hardness is HV1300~1800. White Iron Ball Mill Liner's eutectic carbide is distributed on the base, martensite(the most hard metal matrix organization), in discontinuous network and isolation, which reduces the fragmentation of the matrix effect.

Brinell hardness is sometimes quoted in megapascals; the Brinell hardness number is multiplied by the acceleration due to gravity, 9.80665 m/s 2, to convert it to megapascals. The BHN can be converted into the ultimate tensile strength (UTS), although the relationship is dependent on the material, and therefore determined empirically.
