WebThe Brinell hardness test uses a ball indenter of diameter, D, which is pressed into the surface of the test piece using a prescribed force, F. The time for the initial application of the force is 2 s to 8 s, and the test force is maintained for 10 s to 15 s. The diameter of the indentation, d , is measured after the force has been removed. WebThe Brinell hardness will scale the hardness of materials by the penetration depth of an indenter, which means we need to punch a small pit on the surface of the metal castings. The Rockwell hardness determines the hardness by measuring the depth of penetration of an indenter under a large load compared to the penetration made by a preload.
