\ A weldable, high temperature oxidation resistant alloy with low solidification crack sensitivity and good resistance to strain age cracking. The alloy contains by weight percent, 25% to 32% iron, 18% to 25% chromium, 3.0% to 4.5% aluminum, 0.2% to 0.6% titanium, 0.2% to 0.4% silicon, 0.2% to 0.5% manganese and the balance nickel plus impurities. The Al+Ti content should be between 3.4 and 4.2 and the Cr/Al ratio should be from about 4.5 to 8.
