Sany Cutting rings raw materials is same as wear plate, which all is made of 42CrMo and coat Tungsten Carbide. In concrete pump and other concrete equipment parts, wear plate and cutting rings are important parts in pumping system. High quality is determined by raw materials, but the correct use method can also affect the service life time.
Material: 42CrMo steel body, tungsten carbide.
