Process Features: The metallurgical combination of the two materials is achieved through the liquid fusion process of the two metals, combining the excellent wear resistance of high-chromium cast iron and the good toughness of alloy steel. The striking part is usually made of high-chromium cast iron (Cr20~30%); the handle is mostly made of high-hardness and toughness alloy steel.
