Saw blade substrate selection

1. 65Mn spring steel has good elasticity and plasticity, economical material, good heat treatment hardenability, low heating temperature, easy deformation, and can be used for saw blades that do not require high cutting requirements.
2. Carbon tool steel has high carbon content and high thermal conductivity, but its hardness and wear resistance drop sharply when subjected to a temperature of 200°C-250°C, large heat treatment deformation, poor hardenability, and easy cracking after long tempering time. Manufacturing economical materials such as T8A, T10A, T12A, etc. for knives.
3. Compared with carbon tool steel, alloy tool steel has better heat resistance, wear resistance, and better processing performance. The heat-resistant deformation temperature is 300°C-400°C and is suitable for manufacturing high-grade alloy circular saw blades.
4. High-speed tool steel has good hardenability, strong hardness and rigidity, and less heat-resistant deformation. It is an ultra-high-strength steel with stable thermoplasticity and is suitable for manufacturing high-end ultra-thin saw blades.
