WC-TiC-TaC（NbC）CoCommon knowledge about hard alloy:TaCThe mass fraction in tungsten steel reaches12%～15%At this time, it can increase the ability to resist periodic temperature changes, prevent cracking, and improve the ability to resist plastic deformation.WC-TiC-TaC（NbC）-CoTungsten steel materials have high high-temperature hardness, high-temperature strength, strong oxidation resistance, as well as high wear resistance and heat resistance. This type of tungsten steel combines bothWC-CoreachWC-TiC-CoMost of the best properties of tungsten steel can be used for processing steel materials (primary applications), as well as for processing cast iron and non-ferrous metals, so it is often referred to as universal tungsten steel, especially suitable for processing various high alloy steels, heat-resistant alloys, various alloy cast iron, special hard cast iron and other difficult to machine materials. If the cobalt content is appropriately increased, this type of tungsten steel will have higher strength and toughness, and can be used for rough machining and intermittent cutting of various difficult to machine materials.WC-TiC-TaC（NbC）-CoThe application of substrates in coated tungsten steel is very extensive.
