Grade: RHR-S Hardness: 1570 Bending strength: 3700 Compressive strength: 5500 Density: 14.5 Usage: Suitable for hardness> HRC55 hard material processing, non-metallic materials (nylon, plastic, glass, steel, etc.) tungsten steel metal and carbon to form metal carbides, due to the small radius of carbon atoms, can fill the gap in the metal character of the original lattice and retain the form of the metal, to form an interstitial solid solution. Under appropriate conditions, such that it can continue to dissolve the solid solution of the constituent elements, until saturated. Thus, the composition of which 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.
