Brinell Hardness is a measure of a material's hardness, determined by pressing a hard steel or carbide ball into the surface of the material under a specific load. The diameter of the indentation left in the material is then measured. This value helps to assess the material's resistance to deformation and wear.
The Brinell hardness number (BHN) is calculated by dividing the applied load by the surface area of the indentation. This method is commonly used for testing metals and alloys, providing valuable information for engineers and manufacturers in selecting materials for various applications.
