Rockwell Hardness Conversion Calculator — Frequently Asked Questions
Q1 When should HRC be used vs HRB? ▾
HRB (1/16" steel ball) is used for softer non-ferrous metals and mild steels (0–100 HRB); HRC (diamond cone) is used for hardened steels (20–70 HRC).
Q2 Why are conversions approximate? ▾
Different test methods measure varied combinations of elastic recovery, shear resistance, and work-hardening response.
