The Brinell hardness is designated by the most commonly used test standards (ASTM E10-14 [2] and ISO 6506–1:2005) as HBW (H from hardness, B from brinell and W from the material of the indenter, tungsten (wolfram) carbide). In former standards HB or HBS were used to refer to measurements made with steel indenters.
Hardness comparison. 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.

Rockwell scale. 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 ...
The hardness of abrasion resistant steel is determined by a Brinell hardness test. This test uses a small steel ball to inflict force on a material. The indentation created by the steel ball is then measured and used to calculate Brinell hardness number (BHN). [3]
The Shore durometer is a device for measuring the hardness of a material, typically of polymers. [1] Higher numbers on the scale indicate a greater resistance to indentation and thus harder materials. Lower numbers indicate less resistance and softer materials. The term is also used to describe a material's rating on the scale, as in an object ...
Brinell hardness test. August Brinell (19 June 1849 – 17 November 1925) was a Swedish Metallurgical Engineer. Brinell is noted as the creator of method for quantifying the surface hardness of materials, now known as the Brinell hardness test. His name is also commemorated in the description of a failure mechanism material surfaces known as ...
Hardness. In materials science, hardness (antonym: softness) is a measure of the resistance to localized plastic deformation, such as an indentation (over an area) or a scratch (linear), induced mechanically either by pressing or abrasion. In general, different materials differ in their hardness; for example hard metals such as titanium and ...
