How to distinguish cemented carbide grades?
Carbide how to distinguish between help you answer the following, I hope to help youCommonly used carbide WC as the main component, according to whether to join other carbide is divided into the following 3 categories:(1) tungsten cobalt (WC+Co) cemented carbide (YG), as long as pig iron is processedIt consists of WC and Co which has higher flexural strength, toughness, good thermal conductivity, but heat resistance and poor wear resistance, mainly used for processing cast iron and nonferrous metals. YG hard alloy fine grain (such as YG3X, YG6X), in the same amount of cobalt, the 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.(2) tungsten titanium cobalt hard alloy (WC+TiC+Co) (YT) "the main processing of wrought iron"Because of the hardness and melting point of TiC was higher than WC, so compared with YG, the hardness, wear resistance, hardness increases, bond high temperature, strong antioxidant capacity, and will generate TiO 2 at high temperature can reduce the adhesion. But poor thermal conductivity, low flexural strength, so it is suitable for processing steel etc. the toughness of materials.
(3) titanium cobalt tungsten tantalum carbide (WC+TiC+TaC+Co)) (YW YS) "the main processing of heat resistant steel, high manganese steel, stainless steel and other hard materials processing" in addition to TaC YT hard alloy on (NbC), improve the bending strength, impact toughness, high hardness, wear-resistant and anti oxygen ability. Can be processed and can be made of steel, cast iron and non-ferrous metals. It is often called the universal hard alloy (also known as the universal hard alloy). The following is a variety of grades, density, bending strength, hardness and flexural strength hardness grade use density of use of YG3X 14.6-15.2 132092 is suitable for cast iron, nonferrous metals and alloy steel small alloy steel cutting section of high-speed machining. K01 YG3X YG6A 14.6-15.0 137091.5 for hard cast iron, non-ferrous metalsalloys, also suitable for high manganese steel, hardened steel, alloy steel and semi finishing K05 YG6A YG6X 14.6-15.0 finishing. 142091 it is proved that the alloy processing of chilled alloy cast iron and alloy steel can obtain good results, finishing is suitable for ordinary iron. K10 YG6X YK15 14.2-14.6 210091 for the whole processing of drilling, milling, reaming and alloy cutter. Have high wear resistance and toughness of K15. K20 YK15 YG6 14.5-14.9 138089 is suitable for cast iron, nonferrous metals and alloy non metallic materials at medium cutting speed precision. K20 YG6 YG6X-1 14.6-15.0 150090 is suitable for cast iron, nonferrous metals and alloy non metal material during continuous cutting finishing, discontinuous cutting the semi refined car, fine car, small car, coarse fine car section thread, continuous section semi finishing milling and finish milling, rough and fine hole expansion. K20 YG6X-1 YG8N 14.5-14.8 200090 is suitable for cast iron, cast iron, ductile iron and chromium, High speed machining of nickel stainless steel alloy.
