Abstract
A rolled high Al stainless steel foil for use as a substrate for a catalyst carrier, which comprises more than 12 wt % up to 20 wt % of Al, from 5 to 25 wt % of Cr, from 0.05 to 2 wt %, in total, of at least one element selected from the group consisting of Ti, Nb, Zr, and Hf, and the remainder substantially consisting of Fe and unavoidable elements. The stainless steel foil has an excellent resistance to oxidation in an engine exhaust gas at a temperature of 1150.degree. C. or higher, can be obtained by foil-rolling, and enables a reduction of the exhaust back-pressure and weight of automobile catalyst converters.
