The effects of several compound inoculants on the mechanical property, processability and sensibility of the gray cast iron used in cylinder body are investigated in this article. The results show that tensile strength is higher than that of HT 295 grade, and metallurgy quality is improved for the gray cast iron inoculated using 40%RE+60%75SiFe compound inoculants. While the gray cast iron inoculated with 20%75SiFe+80%Sr compound inoculants has the best process-ability and the least sensibility and the least micro hardness difference. The wear extent of the drill increased obviously with the increase of the micro hardness difference of matrix structure, which shown the homogeneousness of matrix structure of the grey cast iron has great effect on the machinery of the gray cast iron.
