Calculate Brinell hardness number from applied load, ball indenter diameter, and measured indentation diameter.
Method notes
See the description of Brinell Hardness test below. The Brinell Hardness Number (BHN) is calculated from the applied load, the ball indenter diameter, and the mean indentation diameter.
- For background on the Brinell hardness test, see the TriboNet Brinell hardness reference page: Brinell indenter hardness.
- Use applied load in newtons, ball diameter D in millimeters, and mean indentation diameter d in millimeters.
- For further background, consult a Brinell hardness reference and the Brinell scale diagram.
