Enter the load, steel ball diameter, and depression diameter into the calculator to determine the Brinell Hardness of an object.
Brinell Hardness Formula
The following equation is used to calculate the Brinell Hardness number of a material.
- Where P is the applied load (kg-f)
- D is the diameter of the steel ball ( mm)
- d is the diameter of the indentation caused by the steel ball (mm)
Brinell Hardness Definition
The Brinell Hardness is a test performed on a material that describes the overall hardness of the material based on the indentation left during the test.

FAQ
Brinell Hardness is a characteristic of a material that describes it’s hardness through the indentation of a material caused by forcing a steel ball onto the material.
This test is typically performed by placing a small sheet of material beneath a 10mm diameter steel ball, and applied a force of 3000 kgf to the steel ball.
