Selection of matrix of cemented carbide type
1.65Mn Spring steel elastic and plastic good, material economy, heat treatment hardenability, its heating temperature is low, easy deformation can be used to require cutting the blade is not high.
2 Carbon tool steel has a high carbon conductivity rate, but the hardness and wear resistance of the 200℃-250℃ temperature drops sharply, the heat treatment deformation is big, the hardenability is poor, the tempering time is long and easy to crack. For cutting tool manufacturing economic materials such as $literal, t10a, $literal, etc. 3. Alloy tool steel compared with carbon tool steel, heat resistance, good wear resistance, good treatment performance, heat-resistant deformation temperature in 300℃-400℃ suitable for the manufacture of high-grade alloy circular saw blades.
4. High-speed tool steel with good hardenability, hardness and rigidity, heat-resistant deformation less, is a ultra-high strength steel, thermoplastic stable suitable for the manufacture of high-grade ultra-thin saw blades.
