Grade: U83 gravity: 13.8 Hardness: 82.0 elongation: 1230 Usage: widely carbide with high hardness, wear resistance, strength and toughness, heat resistance, corrosion resistance and a series of excellent performance, especially its high hardness and wear resistance, even at 500 ℃ temperature also remained unchanged, at 1000 ℃ still very high hardness. Carbide is widely used as a tool material, such as turning, milling, planer, drill, boring knives for cutting cast iron, nonferrous metals, plastics, chemical fiber, graphite, glass, stone and ordinary steel can also be used to cut heat-resistant steel, stainless steel, high manganese steel, tool steel and other difficult to machine materials. Carbide cutting tools are now new carbon steel equal number of times. Carbide can be used to make drilling tools, mining tools, drilling tools, measuring tools, wear parts, metal grinding, cylinder liners, precision bearings, nozzles, metal molds (such as drawing dies, molds bolts, nuts, mold, and various fasteners dies, carbide excellent performance gradually replace the previous steel mold).
