Web13 nov. 2016 · With the Rockwell testing machine, the hardness is indicated directly on the scale attached to the machine. This dial like scale is really a depth gauge, graduated in special units. For soft materials such as soft steel, copper and aluminum alloys, a 1.6 mm diameter steel ball is used with a 100 kg load and the hardness is read on the ‘B’ scale. Web🕑 Reading time: 1 minute Hardness of a material is defined as its resistance to indentation. Rockwell hardness test measures the permanent depth of indentation on a metal by applying a fixed load using an indenter. The smaller the indentation value, the harder is the material.
