FE-CR-AL BASED ALLOY FOIL AND METHOD FOR PRODUCING THE SAME
摘要
A Fe-Cr-Al based alloy foil having a thickness of 40 mu m or less, which has a chemical composition in mass %, wherein the contents of Cr and Al are 16.0 to 25.0 % and 1 to 8 %, respectively, it contains La and Zr in contents depending on the thickness of the foil so as to satisfy the following formula: 1.4/t </= La </= 6.0/t ...(1); 0.6/t </= Zr </= 4.0/t ...(2) wherein t represents the thickness of the foil in mu m. The Fe-Cr-Al based alloy foil is thin and excellent in the resistance to oxidation and deformation at a high temperature and thus is suitable as a material of a carrier for a catalyst for clarifying a gaseous emission.
