HIGHLY HEAT RESISTANT METALLIC CARRIER FOR AUTOMOBILE CATALYST.

摘要

A highly heat-resistant metallic carrier for an automobile catalyst comprising a metal honeycomb and an outer tube, characterized in that a foil material constituting the metal honeycomb comprises an Fe-Cr-Al alloy, and has a high temperature proof stress in which the proof stress of the above foil material at 600 DEG C and 700 DEG C is, respectively, equal to or higher than 22 kgf/mm<2> and 11 kgf/mm<2> in a state in which the foil material is annealed at a temperature equal to or higher than the temperature of recrystallization of the foil material.
