Hardness conversion HRC, HV and HB for non-austenic steels

Published on 26/08/2021 by Giacomo Bordiga

Vickers hardness testing

This tool converts the harness values to differt scales: Brinell (HB), Vickers (HV) and Rockwell C (HRC). It is base on the conversion data for non-austenitic steels extracted from ASTM E140 standard (Table 1).
