Abstract
A metal sheet having a microstructure relieved of notching, a carrier body having a plurality of sheets, and an exhaust system having the carrier body, are distinguished by a particularly long useful life in an automobile. Moreover, it is possible to bring about flow profiles coordinated exactly with the respective fields of use, so that a particularly efficient or extremely adaptable carrier body for purifying the exhaust gas of automobiles is provided.
Claims31
A metal sheet, comprising:
- an inner region;
- a surface structure having a wave-shaped configuration with wave crests and wave troughs extending in a longitudinal direction, said wave-shaped configuration having a wavelength, a wave height and a ratio of wavelength to wave height lying in a range of 2.0 to 1.3;
- two slits disposed in said inner region, said slits each having at least one respective edge region and a recess in said at least one edge region, said recess having a radius in the range of 0.2 mm to 0.4 mm;
- and
- a microstructure at least partially delimited by said two slits, said microstructure projecting out of said surface structure.
