As shown in Figure 2, the SEM of 900 ℃ and 950 ℃ high chromium cast iron is shown. The content of eutectic carbide M7C3 in high chromium cast iron was calculated by ippimageproplus software, and the result was 15 vol.%. It can be seen from Figure 2 that after quenching, eutectic carbides are distributed in rod and block shape, and some eutectic carbides M7C3 have holes.
