The Rockwell test is generally easier to perform, and more accurate than other types of hardness testing methods. Bu sayfanın çevirisini yap The tests determine the depth which such a ball or cone will sink into the metal, under a given loa within a specific period of time. Laboratory Testing Inc.
Philadelphia, PA (USA) performs microhardness and various hardness test methods and offers the following: Testing of . The oldest of the hardness test methods in common use today, the Brinell test is frequently used to determine the hardness of forgings and castings that have a grain structure too course for Rockwell or Vickers testing.
Therefore, Brinell tests are frequently done on . The Rockwell method is more universal, because it allows for the used of diamond cone and steel ball penetrators. The Vickers method , which only allows for a diamond pyramid penetrator, can be employed in the entire hardness range. However, it is most suitable for tests in laboratories compared to tests in workshops. Heat treating has evolved into a highly complex, precise process that improves characteristics of metal parts.
