Rockwell hardness tests use a preload to establish a zero position before the main load is applied. The main load is then taken away and only the preload remains. Then the distance traveled is measured by the Rockwell …

WebBrinell. The Brinell hardness testing method is similar to the above Rockwell testing method with a couple differences. A typical test on steel uses a 10mm diameter steel (or tungsten) ball with 3,000kg of force. A steel ball is used for most materials; the tungsten ball is used primarily for harder materials like tool steel.
