用である。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a Fe-Cr-Al alloy plate having excellent high temperature strength and oxidation resistance and a foil thereof. The present alloy is suitable not only for a catalyst carrier and a catalytic converter for purifying automobile exhaust gas that are subjected to severe vibration and thermal stimulation in a high temperature oxidizing atmosphere, but also useful for equipment and devices of a combustion gas exhaust system.

ない。In recent years, it has been required to improve the exhaust gas purification efficiency especially at the cold start by strengthening the exhaust gas regulations of automobiles. Therefore, an automobile exhaust gas purifying catalyst device is being developed in which a converter is installed in a position close to a combustion environment and a high temperature exhaust gas reaches a catalyst activation temperature earlier than the initial stage of engine startup to cause a catalytic reaction. Further, since the engine vibration and exhaust gas impact are increased due to the high output and downsizing of the engine, the conventional Fe-Al-Cr alloy has insufficient high temperature strength and oxidation resistance, resulting in honeycomb breakage and cannot be put to practical use. .

There is a problem in that Zr is added to the No. 1, but there is a problem in terms of high temperature strength. Further, in the case where the improvement is made by adding Nb from the viewpoint of high temperature strength, JP-A-4-120247 and JP-A-58-58-
No. 177437. However, when Nb is added, the oxidation resistance is significantly deteriorated, and the oxidation resistance is insufficient for the honeycomb material mounted on the exhaust manifold.

その上限を８％以下に限定する。Next, the reasons for limiting the components of the alloy of the present invention will be described. In addition, 0% is included when there is no lower limit. Al: Al is an indispensable element for ensuring the oxidation resistance and the creep strength in the present invention.
When holding the -Al alloy to a high temperature, Al will be preferentially oxidized than Fe-Cr generates a high Al 2 O 3 film having protective properties to the alloy surface, improves the oxidation resistance. Al content is 5.0
% Or less, a dense Al 2 O 3 coating excellent in oxidation resistance and creep strength is not formed, so the lower limit is set to 5.
It is necessary to add more than 0%. From the viewpoint of oxidation resistance and creep properties, it is desirable to increase the Al content, but if Al exceeds 8%, hot rolling is difficult, so the upper limit is limited to 8% or less.

難となるので、１１％以上２５％以下とした。Cr: Cr not only serves to improve the oxidation resistance of Al, but Cr itself is an element that improves the oxidation resistance. Here, if it is less than 11%, the oxidation resistance cannot be secured, and if it exceeds 25%, the toughness deteriorates and cold rolling becomes difficult, so 11% or more and 25% or less.
【００１１】Ｓｉ：ＳｉはＡｌ同様耐酸化性を高める元

下させるので、その上限を１．５％以下に限定する。Si: Si is an element that enhances the oxidation resistance like Al, but if it is contained in a large amount, it lowers the toughness and the manufacturability, so the upper limit is limited to 1.5% or less.

It was limited to 1.0% or less in consideration of industrial and economical melting technology.

It can be contained in the range of 001 to 0.05%. However, Ce is not included because it deteriorates hot workability and oxidation resistance. Further, since hot rolling becomes impossible, the total amount of lanthanoids is 0.2% or less, and the lower limit is 0.05%.

However, if its content exceeds 0.2%, it will be mixed as ZrO 2 in the Al 2 O 3 film, and this will serve as a diffusion path for oxygen, which will result in accelerating Al consumption. Therefore, the content is set to 0.01% or more and 0.20% or less.
