There has been provided an improved reinforcing web for multicellular honeycomb converter core bodies. The reinforcing web contains at least one flat thin metal strip to which is secured at least one corrugated thin metal strip as by brazing or welding. The reinforcing web is located centrally of the core body and gives the converter bodies hereof sufficient axial strength to survive the severe durability tests imposed by the automotive manufacturers.
