The diameter of the resulting permanent impression in the tested metal is measured and the Brinell Hardness Number calculated as. BHN = 2 P / (π D (D - (D 2 - d 2) 1/2)) (1) where . BHN = Brinell Hardness Number. P = load on the indenting tool (kg) D = diameter of steel ball (mm) d = measure diameter at the rim of the impression (mm) ...
The Brinell Hardness Number is used to convey the hardness of the given material. This Brinell Hardness Number is termed as the BHN and it is the function of the force applied divided by the surface area of the indentation made by the ball on the given material. The units of the BHN are kgf/mm 2. If the BHN number is multiplied by the ...

3.1.5 Brinell hardness number—a number, which is propor-tional to the quotient obtained by dividing the test force by the curved surface area of the indentation which is assumed to be spherical and of the diameter of the ball. 1 This test method is under the jurisdiction of ASTM Committee E28 on
The Brinell hardness test is defined in ASTM E10 is used to calculate Brinell hardness of the metal. It is used on the metal having a rough surface and harsh texture. The Brinell hardness test is used to measure the hardness of light metals like lead and tin, also hard metals like steel and iron. Conclusion:
The method proved reliable and in 1900 the Brinell hardness test was officially born. Today, the Brinell test is performed using a Brinell hardness test unit. The machine presses a tungsten carbide ball into the sample, and then optically measures the diameter of the impression. Indenter sizes: 1, 2.5, 5 and 10 mm. Loads: From 1 kgf to 3000 kgf.
The ratio of testing force F F and the indentation surface A A (spherical segment) serves as a measure for the Brinell hardness value HBW: HBW = 0.102 ⋅ F A (1) (1) H B W = 0.102 ⋅ F A.
