BHN is designated by the most commonly used test standards (ASTM E10-14 and ISO 6506–1:2005) as HBW (H from hardness, B from brinell and W from the material of the indenter, tungsten (wolfram) carbide). Carbide Insert Grade Range Chart. Silicon carbide is a hard covalently bonded material predominantly produced by the carbothermal reduction of silica (typically using the Acheson process). For softer materials, there are alternate scales using a 1500 kg or 500 kg load to avoid excessive indentation. If a file cannot scratch your material, then your material is harder than the file. 0000003094 00000 n 0000001166 00000 n The machine presses a tungsten carbide ball into the sample, and then optically measures the diameter of the impression.
