Brinell hardness


Brinell hardness
(HB or BHN)
   a measure of the hardness of a metal introduced by J. A. Brinell in 1900.
   In the Brinell test (generally used for metals of uniform hardness), a hard object such as a steel ball is pressed into the material being tested. The ball is of a specified diameter, usually 1 centimeter. The Brinell hardness is the amount of force applied to the ball divided by the area of the indentation the ball makes in the material. The result is measured in kilograms of force per square millimeter but should be stated as an empirical reading, without units. For readings up to about HB 500, Brinell hardness is about 0.96 times the Vickers hardness.
