The Industrial Blade Manufacturer believes that a good round blade has to meet several basic characteristics:
In general, the better the material, the higher the hardness achieved by quenching. If the ordinary material is quenched to a very high hardness, then the toughness of the circular blade is destroyed, causing the crack of the blade. Therefore, the quenching hardness of the round blade must be determined by the material. The hardness of the circular blade should be much greater than the hardness of the slitting material.
2. Wear resistance
The wear resistance of the blade is proportional to the hardness. The better the material used for the round insert, the higher the hardness, and the better the wear resistance. Such as 45mm Round Cutter Blade.

3. Heat resistance
Heat resistance means that the steel still maintains the hardness, toughness, strength and wear resistance in the high-temperature environment generated by high speed. The hardness of the round blade is usually measured by the red hardness of the steel, and the cutting speed of the material with higher red hardness can be withstood. The higher.
Stability refers to the degree to which the crystal of the material of the slitting blade changes when the blade is heat-treated. At present, the heat treatment methods of the slitting machine blades are vacuum quenching, salt bath quenching, electric furnace quenching, etc. Different quenching methods have an important influence on the stability of the blade material.
