Purpose: The purpose of this experiment, Hardness Test, is to develop familiarity with the procedure in the operation of different hardness testing machines and Rockwell Hardness. The most important factor is to determine the relationship between hardness and other mechanical properties. Description/Data: The Rockwell hardness test consists of indenting the specified test material with a diamond cone (Rockwell C scale) or hardened steel ball indenter (Rockwell B scale). An indenter is selected from very hard materials. No matter what scale is being used, its indenter is forced into the test material under a beginning load of 10 kg. An indicating device dial follows the movements of the indenter and gauges changes in depth of penetration of the indenter. The resistance of a material to penetrate is a measure of its hardness. We make sure this dial is
