The Rockwell scale is a hardness scale based on indentation hardness of a material. The Rockwell test measures the depth of penetration of an indenter under a large load (major load) compared to the penetration made by a preload (minor load). There are different scales, denoted by a single letter, that use different loads or indenters. The result is a dimensionless number noted as HR… WebThe table below converts Brinell Hardness to Rockwell Hardness scales and vice versa, then compares those to the approximate tensile strength that those scales indicate.
