Title:
FE-CR-AL ALLOY EXCELLENT IN OXIDATION RESISTANCE AND FOIL THEREOF
Document Type and Number:
Japanese Patent JP3247162
Kind Code:
B2
Abstract:
PURPOSE: To make the oxidation resistance of an Fe-Cr-Al alloy at a high temp. excellent by specifying its compsn.
CONSTITUTION: The compsn. of the Fe-Cr-Al alloy is formed of a one contg., by weigh, ≤0.05% C, ≤0.02% N, ≤1.0% Si, ≤1.5% Mn, ≤0.01% S, total ≤0.05% Ti and Nb, ≤ 0.01% Ce, 10 to 28% Cr, 1 to 6% Al and 0.0003 to 0.3% Ca and furthermore contg. 0.01 to 0.20% La and 0.01 to 1.0% Zr so as to satisfy the inequality (A): 0.1≤[Zr wt.%]/[La wt.%]≤20, and the balance Fe with inevitable impurities. In this way, the Fe-Cr-Al alloy excellent in oxidation resistance at a high temp. and foil thereof can be obtd.
