Abstract (en)
A high-carbon austenitic iron-base alloy for wear and corrosion resistant applications is developed for valve seat insert applications when corrosion resistance is required. The alloy comprises 1.8-2.8 wt% carbon, 0.5-3.5 wt% silicon, 12.0-22.0 wt% chromium, less than 1.5 wt% manganese, 2.0-16.0 wt% molybdenum and tungsten combined, 0.05-4.0 wt% niobium and vanadium combined, 0-1.0 wt% titanium, 0.01-0.2 wt% aluminum, 12-25 wt% nickel, 0.05-3.0 wt% copper, and the balance being iron and a small amount of impurities.
