Rockwell C Hardness Conversion
Approximate Conversion Values for Non-Austenitic Steels
ATRONA Test Labs is pleased to bring you this useful quick reference chart showing Rockwell C hardness conversion to Vickers (HV), Brinell (HB), Rockwell A, B & D, Rockwell Superficial Hardness (15-N, 30-N & 45-N), Shore Hardness, and Approximate Tensile Strength (PSI). Best of all, we've designed it so all of this information fits on one side of a standard 8.5" x 11" sheet of paper, or view on your PC or work tablet. Just click to download and save this free PDF!
