WebRockwell scale [HRC] Rockwell [HRC/HRB/ HRA] is one of the most common units used for listing the hardness of machined materials. the test is done by measuring the depth of penetration of a sphere under a large load compared to the penetration made by a reference preload. The Rockwell scale is divided into 9 sub-scales marked by letters A-K. WebThe test measures the hardness by pressing an indentor into the surface of the steel with a specific load and them measuring how far the indentor was able to penetrate. HR15T can be represented as Rockwell Superficial 15-T Scale. The Rockwell Superficial Hardness Tester is used to test thin materials, lightly carburized steel surfaces or parts ...
