Brinell hardness

The hardness of a metal or part, as represented by the number obtained from the ratio between the load applied on and the spherical area of the impressionA cavity, or series of cavities (multiple), machined into a forging die to produce a desired configuration in the workpiece during forging. made by a steel ball forced into the surface of the material tested. The Brinell HardnessThe hardness of a metal or part, as represented by the number obtained from the ratio between the load applied on and the spherical area of the impression made by a steel ball forced into the surface of the material tested. The Brinell Hardness Number (BHN) is determined by measuring the diameter of the impression using a low power microscope, then matching this diameter with the load on a standard table....
