WebThe 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. The Brinell hardness tester used was portable hammer hit, suitable for field use. WebThe Brinell hardness will scale the hardness of materials by the penetration depth of an indenter, which means we need to punch a small pit on the surface of the metal castings. …
