FIELD: mechanical engineering; vehicle internal combustion engines; cleaning of exhaust gases. SUBSTANCE: cellular structure member of catalyst reactor consists of alternating smooth and structurized sheets arranged layer-by-layer, at least one layer of sheet metal being made of semifinished item of thickness greater than that of other layers. All smooth metal sheets are of equal thickness within 0.04-0.06 mm, preferably, 0.05 mm. All structurized sheets are of equal thickness within 0.025-0.045 mm, preferably, 0.04 mm. Smooth and structurized sheets are made of semifinished items of different thickness and/or featuring different properties relative to each other. All structurized metal sheets are 0.01 mm thinner than smooth metal sheets. EFFECT: possibility of use under conditions without loads affecting corrosion resistance. 7 cl, 1 dwg
