Abstract (en)
[origin: EP0480461A1] There is disclosed a ferritic stainless steel essentially consisting of C: not more than 0.03 %, Si: less than 0.25 %, Mn: less than 0.25 %, P: not more than 0.03 %, S: less than 0.001 %, N: not more than 0.03 %, Cr: 15 - 25 %, Al: 3 - 6 %, at least one of REM, Y and alkaline earth metals: 0.01 - 0.2 %, optionally at least one of Nb, V and Ti: 0.05 - 1 % and the balance of Fe and unavoidable incidental impurities. This steel has excellent high temperature oxidation resistance, especially resistance to abnormal oxidation and high toughness and is suitable for manufacturing foil substrate for metallic catalytic converters for automobile exhaust gas treatment.
