PURPOSE: To produce an alloy excellent in high temp. strength and oxidation resistance by constituting an Fe-Cr-Al alloy of specified wt.% of C, Si, Mn, Cr, Al, N, Ti, Zr, La, Ce and Fe.

CONSTITUTION: The componental compsn. of this Fe-Cr-Al alloy is constituted of the one contg., by weight, ≤0.05% C, ≤1.5% Si, ≤1% Mn, 11 to 26% Cr, 1 to 8% Al, ≤0.03% N, 0.01 to 2% Ti and 0.01 to 2% Zr, in which the total content of Ti+Zr satisfies 1.5%<Ti+Zr≤3%, contg. 0.05 to 0.2% La and ≤0.03% Ce, and the balance Fe with inevitable impurities. Furthermore, the content of lanthanoids other than Ce is regulated to 0.001 to 0.05%, and the total content of lanthanoids is regulated to 0.05 to 0.2%. The total content of Ti+Zr+Nb satisfies 1.5%<Ti+Zr+Nb≤3%. In this way, the alloy suitable as a heat resistant material including the material for automotive catalitic converter can be provided.
