1. Steel body: At SKYMECH, we use 65Mn and 30MnB5 alloy steel, whose hardness can be as high as 42-50 HRC. The choice of material is related to the replacement used.

2. Tungsten carbide particles: The crushed raw material tungsten carbide has a double-grain structure and high wear resistance. We can add a tungsten carbide layer to the blade to increase the life of the blade. If you have specific needs, please contact us.



Tips:In general, gravel more land will put higher requirements on the wear resistance of the blade, so the use of 65Mn material blade may be more suitable, because 65Mn material has higher hardness and wear resistance.

For the land with more sand, because the sand does not cause greater wear to the blade like gravel, but it will put forward requirements for the strength and toughness of the blade, at this time, the use of 30MnB5 material blade may be more suitable, because 30MnB5 material has higher strength and certain toughness, and can better resist the impact and extrusion on the sandy land.

However, it should be noted that when choosing the actual blade material, it is also necessary to take into account the specific use environment, work intensity, budget and other factors, and make the most appropriate choice after comprehensive consideration.
