WebIn the Rockwell hardness test, intenders are a small steel ball (or soft objects) and a diamond cone for hard materials. Test Force Test force or load used in the Brinell test is very high. It starts from 1kgf to 3000 kgf, while in the Rockwell test, the test force starts from 10 Kgf (minor) to 60, 100, 150 kgf (primary). Accuracy WebThis will go a long way with your current or future employer.
