ABSTRACT:
A new wrought high silicon heat resistant alloy is provided having the broad composition of about 0.16 to 0.30% carbon, about 3.2 to 4.5% silicon, about 0.8 to 1.5% aluminum, about 17 to 20% chromium, about 12 to 16% nickel, up to about 2% manganese, 0 to 0.07% rare earth alloys and the balance iron with residual impurities in ordinary amounts. The alloy is a fully austenitic hot rolled and annealed chromium and nickel containing alloy having high strength and corrosion resistance.
