Abstract:
1. A method for preparing a corrosion and wear resistant iron (Fe)-based alloy, the method comprising the steps of: (a) weighing 94 to 98% by weight of an Fe—Cr—C alloy and 2 to 6% by weight of a Ti—Al—V alloy as raw material, the raw material consisting essentially of 14.1 to 14.7% by weight of chromium (Cr), 1.41 to 1.47% by weight of carbon (C), 1.78 to 5.46% by weight of titanium (Ti), 0.11 to 0.39% by weight of aluminum (Al), 0.07 to 0.27% by weight of vanadium (V) and the balance of iron (Fe); (b) melting the raw material at 1,600 to 1,800° C.; (c) tapping the molten metal at 1,500 to 1,600° C.; and (d) pouring the molten metal into a mold and casting the molten metal.
