Brinell hardness 500 to 3000
WebHärte und Festigkeit. Die Härte eines Werkstoffs hat nur bedingt etwas mit der Festigkeit des Werkstoffs zu tun, auch wenn die Festigkeit die Prüfverfahren zur Härtemessung, die auf der Eindringtiefe verschiedener Prüfkörper beruhen, beeinflusst. Der Einfluss der Festigkeit kann durch die Messung auf dünnen Filmen zwar reduziert, aber nicht völlig … WebAn alternative method is the Brinell hardness test, which uses a hardened steel (or tungsten carbide) ball indenter with a diameter D of, usually, 10 mm. This is applied under a load P of 500–3000 kg applied for 10–30 s. The diameter of the circular indentation d is measured in millimetres. The hardness number, (HB) is calculated using the ...
