What Does BHN Stand For?

BHN stands for Brinell Hardness Number

The Brinell Hardness Number (BHN) is a measure of a material's hardness based on the indentation hardness of a sample. It is determined by pressing a hard steel or carbide ball of a specified diameter into the material's surface under a defined load. The size of the resulting indentation is then measured, and the BHN is calculated using the load divided by the surface area of the indentation. This metric is commonly used in metallurgy and materials science to assess the hardness and wear resistance of metals and alloys.
