A high-carbon austenitic iron-base alloy with good corrosion and wear resistance, particularly useful for valve seat insert applications when corrosion resistance is required, comprises about 1.8-3.5 wt% carbon, about 12-24 wt% chromium, about 0.5-4 wt% silicon, about 12-25 wt% nickel, about 2-12 wt% molybdenum and tungsten combined, about 0.05-4 wt% niobium and vanadium combined, about 0-1 wt% titanium, about 0.01-0.2 wt% aluminum, about 0.05-3 wt% copper, and less than 1.5 wt% manganese, with the balance being iron and a small amount of impurities.
