high temperature alloy with iron as the matrix, which is directly casting into parts or parts blanks after remelting from qualified parent alloy. Add 15% to the iron matrix? 20% chromium and 25% -45% nickel form a stable Y austenite with good oxidation resistance and corrosion resistance. Add an appropriate amount of evaluation and Mo for solid solution strengthening. The strength level is lower than that of the nickel base foundry high temperature alloy, and the service temperature is below 75CTC. It is mainly used for making guide vanes, turbocharger rotor blades or integral turbine rotor parts for early aeroengines, with the advantage of low price.
