PRODUCTION OF CORRUGATED STAINLESS STEEL FOIL FOR METAL SUPPORT OF CATALYST FOR AUTOMOBILE EXHAUST GAS CLEANUP

摘要

PURPOSE:To improve the corrugatability of foil by increasing the total reduction of area at the time of cold rolling and increasing the strength of stainless steel sheet. CONSTITUTION:The corrugated stainless steel foil for metal support of catalyst for automobile exhaust gas cleanup can be produced by regulating the total reduction of area from the first pass to the final pass in the course of cold rolling after final annealing to =75% and applying corrugating to the resulting stainless steel foil in the as-rolled state at the time of producing the undermentioned corrugated stainless steel foil for metal support of automobile catalyst consisting of a metallic honeycomb structure, where a flat foil made of stainless steel foil and a corrugated foil are alternately rolled in, and a metallic external cylinder.
