Document Type and Number:

Japanese Patent JP2857767

Kind Code:

B2

Abstract:

PURPOSE:To improve heat resisting fatigue property as well as to better brazing and adhesion of precious metal catalyst by setting the surface roughness of a metallic foil made of heat resisting steel used as exhaust gas catalyst support of automobile within a specific range. CONSTITUTION:A catalyst support is constituted as a heat resisting stainless steel plane plate 1 and a wave plate 2 having specific thickness are multiplexically and cylindrically rolled in and they are inserted in a heat resisting stainless steel outer cylinder 3. The plane plate 1 and the wave plate 2 are reciprocally connected to each other with brazing, and a metallic foil made of heat resisting stainless steel having a honeycomb shape is formed. In the above constitution, the surface roughness of the metallic foil is set as 0.7 - 2.0mum. At the time of manufacture, a dull finish roll is used and cold rolling is carried out to obtain the dull finish metallic foil.
