  • Fe-based alloy having corrosion resistance and abrasion resistance and preparation method thereof
    Patent number: 7875134
    Abstract: A corrosion and wear resistant iron (Fe)-based alloy is provided. The Fe-based alloy consists 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). The Fe-based alloy is highly resistant to corrosion and wear. In addition, since the Fe-based alloy is prepared using titanium alloy scrap at reduced cost, it is economically advantageous. Furthermore, the Fe-based alloy is environmentally friendly in terms of resource recycling. Further provided is a method for preparing the Fe-based alloy.
