  We refer to circular saw blades with carbide-tungsten carbide inserts, TCT circular saw blades for short. Today we are going to talk about the choice of substrate for circular saw blades.

  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 require low cutting requirements. Carbon tool steel has high carbon content and high thermal conductivity, but its hardness and wear resistance drop sharply when exposed to a temperature of 200℃-250℃, heat treatment deformation is large, hardenability is poor, and long tempering time is easy to crack. Manufacture economical materials for tools such as T8A, T10A, T12A, etc. Compared with carbon tool steel, alloy tool steel has better heat resistance, wear-resistance, and better handling performance. The heat deformation temperature is 300℃-400℃, which is suitable for manufacturing high-grade alloy circular saw blades. High-speed tool steel has good hardenability, strong hardness and rigidity, and less heat deformation. It is ultra-high-strength steel with stable thermoplasticity and is suitable for manufacturing high-end ultra-thin saw blades.

  The above is about the choice of circular saw blade base. For more details, please visit the extra long wood drill bit .
