When selecting TCT circular saw blades, do you know which factors you have to pay attention? For example, types of cemented carbide, matrix and saw blade diameter. More information is introduced in the following article in detail. Types of cemented carbide At first, you should know that the common types of cemented carbide would include tungsten and cobalt group, with YG as its code name, and tungsten and titanium group, with YT as its code name. Because of the good impact resistance performance of YG cemented carbide, it is widely used in the wooden materials processing industry, for example, it is common to find such model number YG8-YG15, do you know the meaning of such model number? The number behind YG is the percent content of cobalt, the higher content of cobalt inside, the better performance of impact resistance and bending resistance strength, however, on the other hands, its hardness and abrasive resistance would be reduced a little. Therefore you have choose right cemented carbide according to its actual condition. Matrix Firstly, the 65Mn spring steel has better performance of elasticity and plasticity, at the same time, it is more economical. However, its heating temperature is relatively low so that it is easy to be out of shape. Because of these features, it is suitable for saw blade which is not used in high cutting requirements. Secondly, the tool carbon steel has high content of carbon so that its thermal conductivity is very high. However, if the temperature reaches up to 200 Celsius degree and 250 Celsius degree, its hardness and abrasive resistance would be reduced greatly. After heating treatment, it is easy to be out of shape and with poor harden ability performance, what’s worse, if the tempering time is too longer, it is easy to be cracked. In short, it is also the economical raw materials for cutting tools such as T8A, T10A and T12A. Thirdly, compared with tool carbon steel, the alloyed tool steel has good performance of heat resistance, abrasive resistance and treatability. Only under the 300 Celsius degree and 400 Celsius degree, it will be out of shape, therefore it is always used as the raw material of top grade TCT circular saw blade. Fourthly, among all these matrix, the high-speed tool steel has the best performance of harden ability, with strong hardness and rigidity, it is not easy to be out of shape even under high temperature. It is used to manufacture top grade ultrathin saw blade. Let me introduce Flostools to you, which is the professional Circular Saw Blade manufacturer in China.
