A process is disclosed for manufacturing a honeycombed body. Sheet metal (2, 3) having at least partially a structure that forms channels through which a fluid can flow is stacked and/or wound in layers. At least part of the sheet metal layers consists at first of a stratified material (4, 5, 6) with at least one layer of chromium-containing steel (4) and at least one mainly aluminium-containing layer (5, 6). The aluminium-containing layer (5, 6) is homogenised to a large extent during a subsequent thermal treatment carried out at first in a vacuum or in a reducing atmosphere, then in an oxidising atmosphere. The thermal treatment is part of a soldering process during which the contact points between the sheet metal layers are soldered together by adding soldering material (10) to at least some partial areas.
