The total possible penetration depth of the indenters is 0.2mm (HRC) or 0.26mm (HRB) and is divided into 100 parts by HRC method or 130 for the HRB method, so hardness at Rockwells method is:1e=0.002m.

Metal Hardness:The Definite Guide (with Hardness Chart

The Rockwell hardness test uses three test forces and three indenters, which have a total of nine combinations, corresponding to nine scales of Rockwell hardness. The application of these 9 rulers covers almost all commonly used metal materials. There are three commonly used HRA, HRB and HRC, of which HRC is the most widely used. Rockwell Hardness Guide What it is, How to Measure, & The Rockwell hardness number is not the same as the calculated depth differential measurement. Softer metals allow for deeper penetration than harder metals, so the B A value will always be higher on soft metal test subjects than hard metals. The Rockwell hardness scale number appears inverse to the depth differential calculation. Rockwell Hardness Testing and Measure of PlasticsRockwell Hardness Testing Conditions. As the method is extended from metals to plastics, one has to be careful to consider:The effects of temperature:Small changes in temperature can result in first and second order phase transitions which can radically alter the hardness of the material. The effects of viscoelasticity:Unlike metals, plastics are viscoelastic.
