Alloy cast iron for a seal, a seal, and a method of manufacturing the seal are provided. The alloy cast iron for a seal includes 3.8 wt % to 4.2 wt % of carbon, 3.3 wt % to 4.7 wt % of nickel, 2 wt % to 5 wt % of molybdenum, 1.2 wt % to 2.0 wt % of silicon, 16 wt % to 18 wt % of chrome, 0.8 wt % to 1.5 wt % of manganese, and the remaining of iron. Therefore, a seal can be produced using a centrifugal casting method and thus productivity of the seal is improved and the seal having excellent abrasion resistance is produced. |
