A wear resistant alloy is provided having a composition by weight of 1.0-2.5 C, 1.5-4.5 Si, 8.0-20.0 Cr, 9.0-20.0 W and/or Mo, 0.5-2.0 Nb, 20.0-40.0 Fe, and the balance being Ni (>25.0). This alloy provides excellent wear resistance and good hot hardness with relatively low cost compared to prior art nickel base alloys. The alloy has particular use as a valve seat insert materials in diesel fuel internal combustion engines.
