Abstract
A ferritic stainless steel having excellent formability, for example, in a deep drawing procedure, contains 0.04 to 0.1 weight % of C, 1.0 weight % or less of Si, 0.75 weight % or less of Mn, 10 to 30 weight % of Cr, 0.5 weight % or less of Ni, 0.025 weight % or les of N, 2 to 30 ppm of boron, and optionally, 0.005 to 0.4 weight % of an additional alloy component consisting of Al and, further optionally, a further additional alloy component consisting of at least one member selected from 0.005 to 0.6 weight % of Ti, 0.005 to 0.4 weight % of Nb, V, and Zr, 0.02 to 0.50 weight % of Cu, and 0.05 weight % or less of Ca and Ce, the sum of the contents of C and N being 0.0502 weight % or more.
