Abstract:
Process for the production of an iron-chromium-aluminum metal foil with great resistance to high-temperature oxidation, said process comprising:fire aluminizing an iron-chromium supporting ribbon with an aluminum-silicon alloy, thereby producing a foil composed of the following (in % of mass):18-25% Cr4-10% Al0.03-0.08% Ymax. 0.01% Ti0-01-0.05% Zr0.01-0.05% Hf0.5-1.5% Sicontaining also residual iron and impurities resulting from the method of production, whereby the total aluminum contents of the coated metal foil at the surface is at least approximately 7% and does not drop below 3% towards the inside.
