The Brinell hardness test uses a spherical indenter which is pressed, by a precisely controlled force – most commonly 3,000 kgf – into the material being measured. The force builds between two and eight seconds then is sustained for several more to ensure that the indentation is a plastic deformation (see footnote). The diameter of the .Brinell Hardness Test. Brinell hardness test is one of the indentation hardness tests developed for hardness testing. In Brinell tests, a hard, spherical indenter is forced under a specific load into the surface of the metal to be tested. The typical test uses a 10 mm (0.39 in) diameter hardened steel ball as an indenter with a 3,000 kgf (29.42 .The test provides numerical results to quantify the hardness of a material, which is expressed by the Brinell hardness number – HB. The Brinell hardness number is designated by the most commonly used test standards (ASTM E10-14[2] and ISO 6506–1:2005) as HBW (H from hardness, B from brinell and W from the material of the indenter, tungsten .
Brinell Hardness Testing: Involves applying a known load to the surface of the test sample via a hardened steel or carbide ball; . Knoop Hardness Testing: Employs a diamond penetrator to impress a sample; Shore Hardness Testing: Uses the principle of measuring the resistance of a material to indentation; Advanced Techniques in Hardness .
Though loads of 500, 1000, 1500, 2000, 2500, and 3000 N are available in a typical Brinell hardness tester, a load of 500 N is used for testing relatively soft metals such as copper and aluminium alloys, while the 3000 N load is often used for testing harder materials such as steels and cast irons.However, the general rule is that the combination of test load and ball diameter .The Brinell hardness test is an empirical indentation hardness test that can provide useful information about metallic materials.
