Most standard hardness tests for steel, including the Brinell, Vickers and various Rockwell tests, are generally classified as bench testers. This means that the component being tested needs to be taken to the machine for hardness to be determined. In order to test larger pieces, such as forgings, a section would need to be removed from the forging in order for it to be tested. Since this is not…
