Manganese steel, high-speed steel, and tungsten steel are common materials for planing blades, and they have some differences in performance and use.
1. Manganese steel: Manganese steel is a common blade material with high hardness and wear resistance. It is suitable for planing materials with lower hardness, such as wood, plastic, etc. Manganese steel planing blades have a lower cost, but relatively short lifespan and require frequent replacement.
2. High speed steel: High speed steel is a blade material with high hardness and wear resistance, suitable for planing materials with high hardness, such as iron and aluminum. High speed steel planing blades have a long service life and good cutting performance, but their prices are relatively high.
3. Tungsten steel: Tungsten steel is a blade material with extremely high hardness and wear resistance, suitable for planing very hard materials such as hardwood and composite materials. Tungsten steel planing blades have an extremely long service life and excellent cutting performance, but their prices are relatively high.
In summary, manganese steel is suitable for planing materials with lower hardness, high-speed steel is suitable for planing materials with higher hardness, and tungsten steel is suitable for planing very hard materials. The selection of planing blade materials should be determined based on the specific material hardness and planing requirements.
