Abstract

The present invention discloses a medium-chromium heat-resistant ferritic stainless steel and a cold-rolled sheet preparation method and use thereof. The chemical composition of the medium-chromium heat-resistant ferritic stainless steel is: C≤0.020%, N≤0.020%, Si: 0.30%-0.50%, Mn: 0.20%-0.50%, Cr: 17.0%-19.0%, Al: 2.0%-4.0%, Ni: 0.05%-0.30%, Mo: 0.10%-0.30%, Ti: 0.10%-0.30%, with the balance being Fe and unavoidable impurity elements, and 60≤(wAl +wSi )×wCr ≤70, 1.0≤4wNi +8wMo -wMn ≤2.0. The preparation method for the medium-chromium heat-resistant ferritic stainless steel cold-rolled sheet comprises steps of smelting, continuous casting, hot rolling, and cold rolling. The medium-chromium heat-resistant ferritic stainless steel cold-rolled sheet of the present invention combines excellent high-temperature oxidation resistance and electrical resistance properties with good processing performance and corrosion resistance, effectively expanding the application fields of medium-chromium heat-resistant ferritic stainless steel products.
