1. The proportion of alloying components is a vital element in the wear resistance of this selection.
2. Hardness is the capability of the support material to keep high-temperature hardness. In cutting coal stone knives, the surface of the cutter head is 600-800 ° C, that the hardness drops by roughly 50%, and also the material calms and moisturizes the worn teeth.
3. Welding residual pressure. There's a large tensile strain involving the brazing filler metal and the base material, which leads to a drop in the weld power, a powerful cutting force brought on by the impact load, along with an embrittlement of the cemented carbide head.
