<p>An alloy having improved creep resistance and oxidation resistance in the as-cast state contains about 0.35% to 0.75% carbon, about 0.2% to 2% manganese, up to about 2% silicon, about 40% to 55% nickel, about 22% to 33% chromium, about 4% to 6% tungsten, about 2% to 6.5% cobalt, and the balance iron and usual impurities. A preferred composition is carbon 0.45% manganese 1.25% silicon 0.75% nickel 48% chromium 27% tungsten 5% cobalt 3%, balance iron. The alloy is particularly used for furnace components such as radiant tubes and shafts, gas turbines, jet engines, crucibles, internal combustion engines and turbo superchargers.</p> |
