Selection of grades when making circular blade from tungsten steel
- Oct 24, 2018 -

Tungsten steel is also called cemented carbide. The hardness is generally as high as 89~95HRA. For this reason, the tungsten steel product has the characteristics that it is not easy to be worn, hard and not afraid of annealing, but is brittle. However, the material of tungsten steel is a bit higher than other materials, so it is not very popular in the manufacture of circular blade. However, many people do not know how to choose tungsten when considering the material of tungsten steel circular blade. Steel material. There are many grades of tungsten steel, such as tungsten: S1, S2, S3, S4, M1, M2, H3, H2, H1G7, D30, D40, K05K10, YG4C, YG6, YG8, YG9, YL60, YG28YT5, Z20, Z30, etc. Wait. Because of the large number of grades, it is more difficult to choose tungsten steel grades when manufacturing circular blade. However, basically every grade has a series of excellent properties such as high hardness, wear resistance, strength and toughness, heat resistance and corrosion resistance, especially its high hardness and wear resistance, even at a temperature of 500 degrees Celsius. The underlying is basically unchanged, and it has a very high hardness at 1000 degrees Celsius. The choice of tungsten steel grades is very important when manufacturing round inserts. Because this is related to the processing cost and life cycle of the round insert, the selection of the grade must be cautious. In our industry, the YG3, YG6, YG8 and other Y-letters are often used when selecting tungsten steel grades. Because the grades of this kind of tungsten steel are relatively low in price, they are all possessed by the properties of tungsten steel. Therefore, when considering the manufacture of round inserts made of tungsten steel, we should first select the grades starting with the Y letter.
