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 materials.

- 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

**What is Brinell Hardness?**

Brinell Hardness is a characteristic of a material that describes its hardness through the indentation of a material caused by forcing a steel ball onto the material.

**How is Brinell Hardness performed?**

This test is typically performed by placing a small sheet of material beneath a 10mm diameter steel ball and applied a force of 3000 kg to the steel ball.
