<p>A stainless steel sheet with excellent heat and corrosion resistances for a brake disk is provided. Specifically, in mass%, C: less than 0.10%, Si: 1.0% or less, Mn: 1.0 to 2.5%, P: 0.04% or less, S: 0.01% or less, Cr: more than 11.5% but not more than 15.0%, Ni: 0.1 to 1.0%, Al: 0.10% or less, Nb: more than 0.08% but not more than 0.6%, V: 0.02 to 0.3%, and N: more than 0.03% but not more than 0.10% are contained so that 0.03 ‰ {C + N - (13/93)Nb} ‰ 0.10, (5Cr + 10Si + 15Mo - 30Nb + 50V - 9Ni - 5Mn - 3Cu - 225N - 270C) ‰ 45, and {(14/50)V + (14/90)Nb} < N (wherein Cr, Si, Mo, Nb, Ni, Mn, Cu, V, N, and C represent the contents (mass%) of the corresponding elements) are satisfied. With such a composition, the stainless steel sheet for a brake disk can be provided with both excellent heat resistance and excellent corrosion resistance after tempering.</p> |
