Model: W10 - non-magnetic tungsten steel Brand: tungsten steel Standard: Detailed Description: Density: 14.0g/cm3 Hardness: 90HRA bending strength: 1800N/mm2 Usage: plastic magnetic extrusion die, nuclear power plants with a mechanical seal ring Tungsten carbide, especially Ⅳ B, Ⅴ B, Ⅵ B group metal carbides are 3273K above the melting point of which hafnium carbide, tantalum were 4160K and 4150K, is currently known in the highest melting point of the material. Most carbide is very hard, and their hardness greater than 1800kg · mm2 (micro hardness is hardness represents one of the methods used for carbide and hard compounds, microhardness 1800kg · mm2 Mohs an equivalent a hardness of diamond 9). Many carbides difficult to decompose under high temperature, antioxidant capacity than its component metal strong. In all carbides TiC best thermal stability is a very important metal carbide. However, in an oxidizing atmosphere, all the carbides are easily oxidized at high temperatures, can be said that this is a major weakness carbide.
