Hardness Conversion Table
The right hand column show an approximate equivalent tensile strength.
Hardness conversion table. A variety of hardness testing methods are available including the vickers brinell rockwell meyer and leeb tests although it is impossible in many cases to give an exact conversion it is possible to give an approximate material specific comparison table for steels. These conversion charts are provided for guidance only as each scales uses different methods of measuring hardness. This table shows approximate hardness of steel using brinell rockwell b and c and vickers scales. The brinell and rockwell conversion table is the difference between the mild load to the major load applied on the surface of the material for a period of time.
