Brinell Hardness an overview ScienceDirect .

Determination of hardness using a steel ball (Brinell method) The Brinell method (Fig. 6.10) provides for determination of hardness by indenting a hardened steel ball of a certain diameter into the test specimen under the effect of a preset load for a certain period of time (GOST 9012–59). The hardness number in this case is determined as a mean pressure per square metre of a spherical
