Iron-based alloy for internal combustion engine valve seat inserts and the like

   
   

An iron-based corrosion resistant and wear resistant alloy is addressed. The alloy contains (in weight percent) 1.1-1.4% carbon, 11-14.25% chromium, 4.75-6.25% molybdenum, 3.5-4.5% tungsten, 0-3% cobalt, 1.5-2.5% niobium, 1-1.75% vanadium, 0-2.5% copper, up to 1.0% silicon, up to 0.8% nickel, up to 0.6% manganese, and the balance iron. The alloy is suitable for use in valve seat insert applications.
