WebSymbol: HB (500) 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 … WebMar 2, 2024 · The relationship is based on Meyer's index (n) from Meyer's law. If Meyer's index is less than 2.2 then the ratio of UTS to BHN is 0.36. Second general way, relationship between S u (tensile ...

Web√ Brinell Hardness Test. This test is one of the most widely accepted hardness tests used by a machinist. Here a ball of 10mm is used as an indenter to make an impression on the material to help calculate its Brinell hardness value. The ball is held in place for a few seconds, usually 30 seconds, while a force is applied. WebThe Brinell hardness system is one of the most widely used systems for indicating the hardness of metals and alloys. Brinell test uses a desktop machine for applying on a specified load to a hardened sphere of a specified diameter. Brinell hardness number can be represented by HB.
