Abstract
Metallic exhaust gas catalyst carrier body, includes high temperature-resistant steel sheets forming a multiplicity of cells permeable to exhaust gas in a given exhaust gas direction, the steel sheets having slits formed therein substantially transverse to the given exhaust gas direction, the slits, in unused state of the carrier body, being of such quantity and size that for every cross section of each of the steel sheets in the given exhaust gas direction substantially between 5% and 30% of the cross section is devoid of steel due to the presence of the slits.
