ABSTRACT:
A process for production of sheet-metal strip of niobium-stabilized 14% chromium ferritic steel, characterized in that certain steel is subjected to:cold rolling of the hot sheet metal with or without preliminary annealing,final annealing of the sheet-metal strip at a temperature of between 800° C. and 1100° C. for a duration of between 1 minute and 5 minutes and preferably at a temperature of about 1050° C. for a time of about 2 minutes. Steel and exhaust manifold.
