High-strength ferritic stainless steel band and manufacturing method thereof

The invention provides a high-strength ferritic stainless steel band, which comprises the following components in percentage by weight: less than or equal to 0.015 percent of C; less than or equal to 1.0 percent of Si; less than or equal to 1.0 percent of Mn; 10.5 to 17.0 percent of Cr; less than or equal to 0.03 percent of P; less than or equal to 0.01 percent of S; less than or equal to 0.1 percent of Ni; less than or equal to 0.015 percent of N; less than or equal to 0.03 percent of Al; less than or equal to 0.006 percent of O; less than or equal to 0.025 percent of C+N; 10(C+N) to 0.60 percent of Nb or 8(C+N) to 0.30 percent of Ti or more than or equal to 10(C+N) to 0.60 percent of Ti+0.5Nb, wherein the ratio of Nb to Ti is between 1.0 and 2.0; the balance of Fe and unavoidable impurities. The invention also provides a method for manufacturing the steel band, which comprises the steps of smelting, continuous casting, coping, hot rolling, annealing and pickling, cold rolling and pickling and bundling. The steel band has higher strength and lower cost and belongs to the environmental-friendly material.
