The Rockwell scale is a hardness scale based on indentation hardnessof a material. Diamond Pyramid 120kg. The result is a dimensionless number noted as HRA, HRB, HRC, etc., where the last letter is the respective Rockwell scale (see below). The higher the number on the RC scale, the harder the steel is. There are different scales, denoted by a single letter, that use different loads or indenters. Hardness vs Minimum Thickness Chart; Rockwell Scale-Indenter-Load Chart; Contact Us.
