Grade: V20 Hardness: 90 density :14.6-14.9 Tensile Strength: 1750 Uses: It has good toughness and wear resistance relative fitness, mainly used for wire, bar drawing processing mode, but also suitable for cast iron, non-ferrous materials, uneven surfaces and interrupted cutting of rough cars, fine planing, precision milling, general and deep hole drilling, reaming and production of woodworking tools and so on. Tungsten steel Therefore, their composition can vary within a certain range (e.g., titanium carbide, the composition of change between the TiC0.5 ~ TiC), chemical formula does not meet the rules of valence. When the dissolved carbon content exceeds a certain limit (for example, titanium carbide of Ti ︰ C = 1 1:1), the lattice pattern will change, so that the original metal lattice into another form of metal lattice, when the Mesenchymal solution called mesenchymal compounds. Metal carbides, especially Ⅳ B, Ⅴ B, Ⅵ B melting point metal carbide in the above 3273K, wherein the hafnium carbide, tantalum, respectively, 4160K and 4150K, is currently known 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).
