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.
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 superficial, hardness, and Shore Scleroscope hardness of nonaustenitic steels including carbon, alloy, and tool steels in the as-forged, annealed, normalized, and quenched and tempered ...
Notes. ^ Hardness can vary by several hundred percent depending on the pretreatment, see e.g. Iron#Mechanical properties and Angelo Basile; Fausto Gallucci (2011). Membranes for Membrane Reactors: Preparation, Optimization and Selection. John Wiley & Sons. pp. 30–.
A PDF document that shows the Rockwell hardness values for various metals and alloys using different scales and loads. Compare the hardness of steel, stainless steel, aluminum, brass, copper, and more with this chart.
The Rockwell scale is a hardness scale based on indentation hardness of a material. The Rockwell test measures the depth of penetration of an indenter under a large load (major load) compared to the penetration made by a preload (minor load). [1] There are different scales, denoted by a single letter, that use different loads or indenters.
18 gru 2023 · The most commonly used indentation hardness tests for metal materials are Brinell, Rockwell, and Vickers hardness tests. The hardness value indicates a material’s ability to resist plastic deformation caused by the intrusion of another object.
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.
