Impact fatigue-resistant wear-proof alloy cast iron

The antiwear alloy cast iron resisting impact fatigue is produced by adding waste steel and Si, Mn elements to pig iron or iron alloy smelted with waste Cr-V-Ti slag, Ni slag and W slag through modification and strong toughening, and may be used to manufacture grinding balls and bar, hammer and lining. The times of impact fatigue are greater than 15 thousands and hardness is HRC 46-63 with a breaking rate less than 1%. It has high performance and low cost.
