New Type of Metal Substrates for Catalytic Converters Durability for Elevated Temperature 2007-01-1264

As a result of higher exhaust gas temperature for an improvement of fuel consumption, catalytic converters must be much more durable at high temperature. To satisfy such requirements, we have developed an advanced metal substrate using newly developed stainless Fe-Cr-Al foil, which contains more than 7.5 mass% of aluminum. The developed foil elongates durable lifetime about 4 times compared with the conventional foils in high temperature oxidizing atmospheres. The newly developed metal substrate is suitable for exhaust systems which is used under conditions of high exhaust gas temperature above 1000 °C.
