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 . See more

These approximate relationships between hardness and tensile strength do not apply to nonferrous metals, with the possible exception of certain aluminum alloys. Related: Brinell Hardness Testing Equation. Table A Brinell Hardness to Rockwell Hardness Conversion TableRockwell hardness test measures the permanent depth of indentation on the material by applying a fixed load using an indenter. The smaller the indentation value, the harder is the material. The Rockwell hardness test follows the principle of the differential-depth method. Here, the indenter makes a residual depth called the indent and it is .Hardness testing blocks, made of carbon steel are used to calibrate metal hardness testers and come in various standard nominal values, such as 25 HRC, 45 HRC, 65 HRC, 90 HRB, and 83 HRA.
