Product description

Basic characteristics of cemented carbide round blades

1. Hardness

Generally, the better the material, the higher the hardness obtained by quenching. If a common material is quenched to a very high hardness, the toughness of the round blade will be destroyed and the blade edge will crack. Therefore, the quench hardness of round inserts must depend on the material. The hardness of the round blade should be much greater than the hardness of the cutting material. Typically, the quench interval for heat treatment is HRC 55-64.

2. Wear resistance

The wear resistance of the blade is proportional to the hardness. The better the material used for round inserts, the higher the hardness and the better the wear resistance.

3. Heat resistance

Heat resistance refers to the hardness, toughness, strength and wear resistance of steel. They stay in a high temperature environment generated at high speed. Generally, the quality of a round blade is measured by the red hardness of the steel. The higher the red hardness, the higher the cutting speed the material can withstand.

4. Stability

Stability refers to the degree of crystallinity change of the slitting blade material after the blade is heat-treated. At present, the heat treatment methods of slitting machine blades include vacuum quenching, salt bath quenching, electric furnace quenching, etc. Different quenching methods have a great influence on the stability of the blade material.
