An iron-based corrosion resistant and wear resistant alloy. The alloy can comprise (in weight percent) 0.005-0.5% boron, 1.2-1.8% carbon, 0.7-1.5% vanadium, 7-11% chromium, 1-3.5% niobium, 6-11% molybdenum, and the balance including iron and incidental impurities. Alternatively, the Nb content can be replaced or combined with Ti, Zr, Hf and/or Ta such that 1%<(Ti+Zr+Nb+Hf+Ta)<=3.5. The alloy has improved hot hardness and high temperature compressive strength and is suitable for use in elevated temperature applications such as in diesel valve seat inserts. |
