Zusammenfassung:In present paper, the 3-body abrasion andimpact fatigue resistance of a 12％Cr-2.65％C-1.4％Sihigh Cr cast iron are comprehensively evaluated.The results indicated that the lower the C contentof the martensitic matrix, the better the impactfatigue resistance of the iron. The retainedaustenite is always harmful to both 3-bodyabrasion and impact fatigue resistances. Thelow C content martensitic matrix free fromretained austenite is suitable for making grindingballs.
