Abstract
Fe--Cr--Si steel sheet having an excellent corrosion resistance and high toughness and method for manufacturing the same; the amount of Cr is about 10-30 wt %, the total amount of C and N is not more than about 100 ppm and the remainder consists of Fe and incidental impurities; when a cast piece of this steel is subjected to hot rolling to roll into a thickness of not more than about 3 mm, the hot rolled sheet can be subjected to cold rolling or to warm rolling without annealing.
