摘要 |
Process for manufacturing a foil of ferritic stainless steel having a high aluminum content, which can be used in particular for a catalyst support in a motor-vehicle exhaust, wherein a ferritic stainless steel sheet of the following composition: 0.005%<carbon<0.060% 10%<chromium<23% 0.1%<aluminum<3% 0.003%<nitrogen<0.030% 0.1%<manganese<2% 0.1%<silicon<2% rare-earth elements in a proportion of between 0.03% and 0.15%, is subjected to: plating between two sheets of aluminum in order to obtain a laminate, rolling the laminate to a thickness of 0.03-0.25 mm to form a foil, static diffusion annealing the foil in a hydrogen atmosphere, and finish rolling greater than 20%.
