Steel hardness conversion chart: Shows equivalents using Brinell, Rockwell B and C and Vickers scales. These values are approximate and for guidance only. Also hardness ranges for heat treated steel.
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
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.
Approximate equivalents between the Brinell and Rockwell hardness scales, as well as their rough correlation to material tensile strength. Hardness testing of steel is typically done on one of two scales, Rockwell or Brinell.
Hardness Conversion Chart with standards including Brinell, Rockwell B scale, Rockwell C scale, Vickers and others.
10 Σεπ 2024 · Our calculator can convert steel hardness between different scales in two steps: Select which hardness number you want to convert from. You can choose from the following: Brinell hardness number; Rockwell C scale; Rockwell B scale; and. Vickers hardness number. Enter the hardness number. The calculator will convert it to all the other remaining ...
These corrections are approximate only and represent the averages to the nearest 1/2 Rockwell number. 1: A 10 mm steel ball was used for 450 BHN and below. A 10 mm carbide ball was used above 450 BHN. Numbers were developed by Wilson Instruments in the Wilson Standards laboratory and are not derived from ASTM.
