Maurice Stewart, in Surface Production Operations, 2021. 6.7.6.4 Overview of Brinell hardness testing. The Brinell hardness lab test method consists of indenting the test material with a 10-mm-diameter hardened steel or carbide ball subjected to a load of 3000 kg. For softer materials, the load can be reduced to 1500 kg or 500 kg to avoid excessive indentation.
Specifications: - Cr. 11- 14 % - Cr. 25- 27 % - Hardness 450-550 BHN The Classifying Chamber Liner of a ball mill is mainly for fine crushing. Therefore, practice little balls was recognize to be more active as this expand the cover area of media and improves the crushing effect.
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.
The performance of high Cr balls in secondary grinding depends on the abrasive/corrosive environment of the mill. In most secondary Au, Cu, and Mo grinding, the relative wear rates of high Cr compared to forged steel show a performance improvement of 25 – 30%, similar to that seen in primary grinding.
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.

Choose samples of material of different hardness, center punch them and get a visual size of the indent. If you can get some calibration coupons from a hardness tester, you could get the hardness quite closely. Spark testing can give you and indication of the chemistry but not the harness.
