To meet demands for auto mobiles to be more friendly to the environment, NIPPON STEEL & SUMIKIN MATERIALS has developed extra-thin metal substrates for catalytic converter (20µm). These substrates have attracted wide attention as they exhibit high emission cleaning efficiency, high power efficiency and compactness.
We have also developed the new stainless steel foil that bears an ultra high temperature of more than 1000°C, caused by high demand for the improvement of fuel consumption. Together with the thermal stress-strain analysis and simulation technologies, We offers as much technical services as possible that precisely cope with vairous advancing demands from automobile manufacturers

Features
(1)NS honeycomb can endure severe conditions at close-coupled position to engine where  low pressure loss and high vibration resistance are required, and increase emission conversion rate to the maximum.
(2)Making use of the ”advantages of metal features” such as high temperature durability, low pressure loss,and low heat capacity for quick light-off, NS honeycomb are widely used for vehicles with gasoline engines with high power , those with diesel engines and motorcycles etc.
(3)NS honeycomb can meet a variety of customer’s demands, because of its design flexibility for honeycombs size, stainless steel foils thickness, and cell densities etc.
