What kinds of carbide knives do you have? Write out its main functions and uses.
(2) tungsten titanium cobalt (WC+TiC+Co) cemented carbide (YT), such as YT5, YT15, YT30 and so on.Because of the hardness and melting point of TiC is higher than WC, so compared with YG, its hardness, wear resistance, red hardness increase, bonding temperature is high, antioxidant ability is strong, and in high temperature will produce TiO 2, can reduce bonding. But the thermal conductivity is poor and the bending strength is low, so it is suitable for the processing of steel and other tough materials.
(3) tungsten tantalum cobalt (WC+TaC+Co) cemented carbide (YA);The addition of TaC (NbC) on the basis of YG cemented carbide improves the hardness and strength, thermal shock resistance and wear resistance at room temperature, high temperature, and can be used to process Cast Iron and stainless steel.(4) tungsten, titanium, tantalum, cobalt (WC+TiC+TaC+Co) and hard alloy (YW), such as W1, W2 and so on.On the basis of YT cemented carbide, TaC (NbC) is added to improve the flexural strength, impact toughness, high temperature hardness, oxygen resistance and wear resistance. Both can process steel, but also the processing of cast iron and non-ferrous metals. Therefore, it is often called universal cemented carbide (also known as universal cemented carbide). At present, mainly used for processing heat-resistant steel, high manganese steel, stainless steel and other difficult materials.
The commonly used cemented carbides are mainly based on WC, and are classified into the following categories whether or not they are added to other carbides:(1) tungsten cobalt (WC+Co) cemented carbide (YG);It consists of WC and Co, has high flexural strength toughness, good thermal conductivity, but poor heat resistance and wear resistance, mainly for the processing of cast iron and non-ferrous metals. YG hard alloy fine grain (such as YG3X, YG6X), in the same amount of cobalt, its hardness wear resistance than YG3, YG6 high strength and toughness is poor, suitable for machining hard cast iron, austenitic stainless steel, heat-resistant alloy, hard bronze.
