<p>The present invention provides an Fe-Cr-Al-based alloy for catalyst carriers and a foil thereof having a thickness of 40 mum or less, the alloy and the foil improved in the oxidation resistance at high temperatures and having excellent deformation resistance. Specifically, the present invention provides an Fe-Cr-Al-based alloy foil and a manufacturing method thereof, comprising 16.0 to 25.0 mass % of Cr, 1 to 8 mass % of Al, La, Zr, and the balance being Fe and incidental impurities. The contents by mass % of La and Zr meet the following ranges when the foil thickness thereof is t mum:<paragraph lvl="0"><in-line-formula>1.4/t<=La<=6.0/t (1)</in-line-formula><paragraph lvl="0"><in-line-formula>0.6/t<=Zr<=4.0/t (2)</in-line-formula>The Fe-Cr-Al-based alloy foil may further comprises Hf and the balance being Fe and incidental impurities, wherein the contents by mass % of La, Zr, and Hf meet the following ranges:<paragraph lvl="0"><in-line-formula>1.4/t<=La<=6.0/t (1)</in-line-formula><paragraph lvl="0"><in-line-formula>0.4/t<=Zr<=2.0/t (3)</in-line-formula><paragraph lvl="0"><in-line-formula>0.5/t<=Hf<=2.0/t (4)</in-line-formula></p> |
