Hardness & Tensile Strength Conversion — Brinell, Rockwell B & C Scales
Why Hardness Matters Hardness testing is the quickest way to verify a material’s heat treatment and estimate its tensile strength without destroying the part. In practice, you’ll encounter three scales constantly: Brinell (HB), Rockwell B (HRB), and Rockwell C (HRC). Conversion Table — Steel These conversions are approximate and apply to carbon and alloy steels. … Read more
