Rockwell to Brinell conversion chart (Brinell, Rockwell A,B,C) Struers hardness conversion table (Vickers, Brinell, Rockwell B,C,D) This page was last edited on 18 December 2023, at 21:15 .A Rockwell hardness tester. 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). [1] There are different scales, denoted by a single letter, that use different loads or indenters. The hardness of steel depends on several factors, such as its composition, manufacturing, and heat-treating processes.The different hardness scales use different loads, different indentor shapes, and different measurements to obtain the hardness number. There are no straightforward formulae to establish relationships between the different scales, making .
