HARDNESS COMPARISION TABLES. Vickers, Brinell and Rockwell hardness as well as tensile strength in steel and cast steel. Table A.1 Conversion of hardness to hardness and hardness to tensile strength for unalloyed and low-alloyed steels and cast steels. The table values are guide values.
Brinell and Rockwell Hardness Conversion Chart - These Conversion Tables presents data in the Rockwell A, B, C, D, E and F hardness range on the relationship among Brinell hardness, Vickers hardness, Rockwell and Shore Scleroscope hardness
MATERIAL HARDNESS CROSS-REFERENCE CHART - Chart showing a cross-reference of hardness spome common measurement scales, including ROCKWELL A, B, C and D, BRINELL, VICKERS and KNOOP.
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.
The table below converts Brinell Hardness to Rockwell Hardness scales and vice versa, then compares those to the approximate tensile strength that those scales indicate.
