What are the meanings of cemented carbide codes, such as YW, YS30, YN10?Which company made its own brand? What is the composition?
YW refers to the national standard brand. YS30 and YN10 are made by the company themselves. The brand is made up of the largest cemented carbide producer in China, Zhuzhou 601 (Zhuzhou cemented carbide group).
Hard alloy is one of the people familiar with the tools and materials, it is very difficult to weld by hard metal carbides (we, Tie) of powder metallurgy with CO, MO and NI as sintering binder. Its mechanical, physical and mechanical properties depend mainly on the kinds of metal carbides, properties, quantities, grain sizes, types and components of binders.In cemented carbides, the proper addition of Tie increases the content of hard Tic, and the higher the hardness of the alloy. The more the content of cobalt in the bonding phase, the lower the hardness of the alloy. Therefore, the hardness of We-Tie-eo alloy is higher than that of We-eo alloy. The hardness of We-eo alloy can be increased by adding Tae or Nbc. The higher the hardness of the cemented carbide, the better the wear resistance, but the lower the strength (bending), and the addition of Tac will improve the blade strength, while strengthening the blade resistance to fragmentation and breakage, fatigue strength also increased. Generally, the higher the hardness, the lower the toughness. In China's Cemented Carbide standard YB850-75, most carbide grades are We-Co (YG) and We-Tie-Co (YT) two.Domestic hardness alloy grade control: GB, brand ISO, P10, P20, M10, M20, K01, K10, K20, K30, domestic uniform brand YT15, YT14, YT5, YW1, YW2, YG3, P30, YG6x, YG6, YG8
Y is the abbreviation of "hard". The letter behind is the abbreviation of metal material, such as "L" is "aluminum", "YL" is "hard aluminum". The number should be related to the alloy composition.
