摘要: A steel sheet for a brake disc contains, on a mass percent basis, 0.02% or more and less than 0.10% C, 0.6% or less Si, more than 0.5% and 2.0% or less Mn, 0.06% or less P, 0.01% or less S, 0.05% or less Al, 11.0% to 13.5% Cr, 0.01% to 0.30% Ni, 0.10% to 0.60% Nb, 0.03% or more and less than 0.10% N, more than 0.0010% and 0.0060% or less B, and the balance being Fe and incidental impurities, and the steel sheet after quenching has a hardness of 32 HRC to 40 HRC on a Rockwell hardness scale C (HRC).
