Grade: NA10 Application: non-magnetic particle size: 0.8 Specific Gravity: 14.36 Hardness: 91.3 tungsten steel (alloy) 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 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 resistant hot steel, stainless steel, high manganese steel, tool steel and other difficult to machine materials. Now the new carbide cutting hundreds of times equal to carbon steel.
