WebbRockwell hardness test is one of the most common indentation hardness tests, that has been developed for hardness testing. In contrast to Brinell test, the Rockwell tester measures the depth of penetration of an indenter under a large load (major load) compared to the penetration made by a preload (minor load).

WebbThe 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. Webb12 okt. 2024 · The Rockwell C scale is good for measuring hardened steel. Rockwell B is better for softer steel or relatively hard aluminum. For softer aluminum, you may need to use the Rockwell E scale (1/8-inch diameter ball with a 100 kg load) or the Rockwell F scale (1/16-inch diameter ball with a 60-kg load).

WebbThe same is true of knives. Generally higher HRC means better edge retention as well as a few other properties, but this is not the end all be all. Between two identical steels at different HRCs you can make better assumptions. And so, in general but loosely so, below 54 HRC is soft, 54-60 HRC is medium, 60 HRC and higher is hard.
