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.
