OXIDATION-RESISTANT METAL FOIL, ITS USE AND METHOD FOR ITS PRODUCTION |
摘要 |
The invention relates to iron-chromium-aluminium metal foil which is resistant to high-temperature oxidation. Said metal foil is produced by hot-dip aluminizing an iron-chromium support band with an aluminium-silicon alloy. The foil has the following composition in weight percent: 18-25 % Cr. 4-10 % Al, 0.03-0.08 % Y, max. 0.01 % Ti, 0.01-0.05 % Zr, 0.01-0.05 Hf, 0.5-1.5 % Si. It also contains residual iron and impurities resulting from the method of production. The total aluminium content of the coated metal foil is at least 7 % near the surface and not less than 3 % further inside. |
