ASSAB XF-30 Carbide Assab Assab XF-30 tungsten steel XF-30 Grit: fine particles 0.8-1 (um) Cobalt content: 15 (%) Density: 14 (g/cm3) Hardness: 89.5 ( HRA) Flexural strength: 390 (kg/mm2) tungsten steel used for carbide and hard compounds, microhardness 1800kg · mm2 equivalent of a diamond a Mohs hardness 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. Uses: 1. Leadframe, EI sheet 2. Nozzles, pumping line mode 3. Cutter 4. Powder molding 5. Continuous Dies
