This is a method used to determine the hardness of a metal. If you know the type of metal and the hardness, this will tell you the Tensile Strength of the metal and how well it was heat treated. The method uses a ball or a pin to strick the metal and leave a small indention. The size and depth that the ball makes in the metal is inversely proportional to the hardness. Using the scale, you can then determine if the part has completed the proper heat treatment as required by the Engineering drawing. There are 3 Rockwell scales: A, B, C. Rockwell C scale is for the hardest of metals such as steel. Rockwell B is for metal such as soft aluminum and A is for even softer metals.
