Abstract:
1. A stainless steel sheet with excellent heat and corrosion resistances for a brake disk consisting of, in mass %: C: not less than about 0.02% but less than about 0.10%, Si: from about 0.05% to about 1.0%, Mn: from 1.00% to about 2.5%, P: about 0.04% or less, S: about 0.01% or less, Cr: more than about 11.5% but not more than about 15.0%, Ni: from about 0.1% to about 1.0%, Al: about 0.10% or less, Nb: more than 008% but not more than about 0.6%, Co: 0.01% to 0.53%, V: from about 0.02% to about 0.3%, and N: more than 0.03% but not more than about 0.10% so that the following expressions (1) to (3) are satisfied: (wherein Cr, Si, Mo, Nb, Ni, Mn, Cu, V, N, and C represent the contents (mass %) of the corresponding elements), and the balance Fe and inevitable impurities and has a hardness of 32 HRC or more after tempering at 600° C. for 2 hours.
