What kinds of materials are there in the steel wire wheel? That brand of wire wheel is the best in the market. Answer in detail. high mark

The steel wire roller is a kind of mold that deforms metal at room temperature, and its precision is very high. When rolling metal, it is subjected to great periodic extrusion force and circumferential friction, and the working conditions are harsh. Its damage forms are: wear, fracture and tooth collapse. The main materials of steel wire roller are Cr 12MoV or Cr 12, as well as 9SiCr and CrWMn. The former has high hardenability, high red hardness and wear resistance, while the latter has poor hardenability and is rarely used. To improve the microstructure and toughness of steel and further increase the wear resistance.
