250-469: Is being fitted to American Humvees . [REDACTED] Media related to Remote weapon systems at Wikimedia Commons Brinell scale The Brinell scale / b r ə ˈ n ɛ l / characterizes the indentation hardness of materials through the scale of penetration of an indenter, loaded on a material test-piece. It is one of several definitions of hardness in materials science . Proposed by Swedish engineer Johan August Brinell in 1900, it

275-549: Is calculated in both standards using the SI units as where: When quoting a Brinell hardness number (BHN or more commonly HB), the conditions of the test used to obtain the number must be specified. The standard format for specifying tests can be seen in the example "HBW 10/3000". "HBW" means that a tungsten carbide (from the chemical symbol for tungsten or from the Spanish/Swedish/German name for tungsten, "Wolfram") ball indenter

300-414: Is multiplied by the acceleration due to gravity, 9.80665 m/s , to convert it to megapascals. The Brinell hardness number can be correlated with the ultimate tensile strength (UTS), although the relationship is dependent on the material, and therefore determined empirically. The relationship is based on Meyer's index (n) from Meyer's law . If Meyer's index is less than 2.2 then the ratio of UTS to BHN

600-407: Was the first widely used and standardised hardness test in engineering and metallurgy . The large size of indentation and possible damage to test-piece limits its usefulness. However, it also had the useful feature that the hardness value divided by two gave the approximate UTS in ksi for steels. This feature contributed to its early adoption over competing hardness tests. The typical test uses

625-427: Was used, as opposed to "HBS", which means a hardened steel ball. The "10" is the ball diameter in millimeters. The "3000" is the force in kilograms force. The hardness may also be shown as XXX HB YY D . The XXX is the force to apply (in kgf) on a material of type YY (5 for aluminum alloys, 10 for copper alloys, 30 for steels). Thus a typical steel hardness could be written: 250 HB 30 D . It could be
