Selection of cemented carbide saw blade (1)

1. 65Mn spring steel has good elasticity and plasticity, economic material, good hardenability in heat treatment, low heating temperature and easy deformation, which can be used for cutting saw blades with low requirements.

2. Carbon tool steel with high carbon thermal conductivity, but the hardness and wear resistance of 200℃-250℃ temperature drop sharply, heat treatment deformation, poor hardenability, long tempering time easy to crack. Manufacturing economic materials for cutting tools such as T8A, T10A, T12A, etc.

3. Compared with carbon tool steel, alloy tool steel has better heat resistance, wear resistance and processing performance. The heat resistance deformation temperature is between 300℃ and 400℃, which is suitable for manufacturing high-grade alloy circular saw blade.

4. High speed tool steel has good hardenability, strong hardness and rigidity, and less heat resistance deformation. It is super high strength steel, stable thermoplastic suitable for manufacturing high-grade ultra-thin saw blades.
