    Brinell hardness measurement is a rough measure of the material properties of a sample It involves using a hard ball to indent the material being tested, and then measuring the size of the indentation The larger the indentation, the softer the material is since the ball was able to penetrate deeper Sounds pretty simple, right? This process actually has many variables that can affect the end· There is another variable—the type of ball used Brinell is expressed as an “HBW” where the last letter indicates the type of ball used – ‘W’ for tungsten carbide, ‘S’ for hardened steel So the Brinell is a calculation?
