What Is The Brinell Hardness Test?

Brinell Hardness Test

The Brinell Hardness Test is a method used to determine the hardness of steel by measuring the resistance to indentation. In this test, a hard steel or tungsten carbide ball is pressed into the surface of the steel sample under a specific load, and the diameter of the resulting indentation is measured. The Brinell Hardness Number (BHN) is then calculated, providing a numerical value that represents the material's hardness. In steel processing and manufacturing, the Brinell test is crucial for quality control and material selection, as it gives insights into the steel's strength, wear resistance, and suitability for various applications.
