Tungsten carbide — a chemical compound of carbon and tungsten (semikarbid monocarbide and tungsten). It is comparable in hardness to diamond and has a high wear resistance, oxidation resistance and extremely high melting point.
Tungsten carbide is used extensively in tools exceptional hardness and corrosion resistance. It is also used for wear-resistant surfacing parts that operate under conditions of intense abrasive wear, in the manufacture of drills, disc cutters and electrodes. Autogenous welding electrode WSC brands and SFTC G21-GF-55-CG (DIN 8555), filled with melted crushed tungsten carbide and nodular, used for surfacing on low-alloyed and unalloyed steels, the tool cutting edges. For electrical carbide hardfacing on low alloyed and unalloyed steels, used special electrode filled with spherical tungsten carbide grade WSC E21 UM-GF-60-CG. Such electrodes as E21-UM-60-CGZ sintered and compacted used for surfacing parts subject to great wear by friction. Autogenous flexible welding electrode with melted crushed tungsten carbide G21-UM-55-CG is used for surfacing on Austenic and ferritic rods for cast iron, deep drilling in the equipment, screw conveyors, and so on.
