Web28 okt. 2024 · How hard is Rockwell C25? attainable Rockwell hardness is C20-C25. Melting point is 2750° F. Yield strength is 60,000-105,000 psi. What is harder Rockwell B or C? It depends on what you’re measuring. The Rockwell C scale is good for measuring hardened steel. Rockwell B is better for softer steel or relatively hard aluminum. WebThe chief advantage of Rockwell hardness is its ability to display hardness values directly. The result is a dimensionless number noted as HRA, HRB, HRC, etc., where the last letter is the respective Rockwell scale. The Rockwell C test is performed with a Brale penetrator (120°diamond cone) and a major load of 150kg.
