YF15 tungsten steel: Hardness: 86.2 Density: 14.5 Tensile strength: 2253 Application: It has excellent strength and toughness, suitable for the production of drawn mold, durable wear parts and pressed parts and carbide automatic presses mold cores. Tungsten steel 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. New carbide cutting speeds hundreds of times equal to carbon steel. Can also be used to make drilling tools, mining tools, drilling tools, measuring tools, wear parts, metal grinding, cylinder liners, precision bearings, nozzles.
