  • LOW COST, CORROSION AND HEAT RESISTANT ALLOY FOR DIESEL ENGINE VALVES
    Publication number: 20020044882
    Abstract: A low cost, highly heat and corrosion resistant alloy useful for the manufacture of diesel engine components, particularly exhaust valves, comprises in % by weight about 0.15-0.65% C, 40-49% Ni, 18-22% Cr, 1.2-1.8% Al, 2-3% Ti, 0.9-7.8% Nb, not more than 1% Co and Mo each, the balance being essentially Fe and incidental impurities. The Ti:Al ratio is ≦2:1 and the Nb:C weight % ratio is within a range of 6:1 and 12:1. Ta may be substituted for Nb on an equiatomic basis.
    Type: Application
