Steel Hardness Conversion Table

This table shows approximate hardness of steel using Brinell, Rockwell B and C and Vickers scales. These conversion charts are provided for guidance only as each scales uses different methods of measuring hardness. The right hand column show an approximate equivalent tensile strength.
