The Brinell test uses a hardened steel or carbide ball with a diameter of 10 mm as an indenter with a load of 3000 kgf to be applied on the material. Due to the high load applied, this test is often used to test hardened steels, although for softer materials the load can be reduced to avoid excessive indentation.

Symbol: HB (Tungsten 3000) The Brinell Hardness Test, commonly used for metallic materials, determines hardness by applying a known load (3000, 1500, or 500 kgf) to the surface of the test specimen via a hardened steel or diamond ball of prescribed size (10 mm in diameter).. The size of the permanent impression on the specimen surface is converted into a Brinell Hardness Number (HB) …

The test involves pressing a hardened steel ball into the test material. The ball is 1, 5 or 10 mm in diameter and is pressed into the surface with an applied load of 30, 300 or 750 kgf. The ball size and load used increase with the hardness of the material.
