Abstract (en)
[origin: EP3208357A1] A high-carbon steel sheet includes: a chemical composition represented by, in mass%, C: 0.30% to 0.70%, B: 0.0004% to 0.0035%, and others; and a structure represented by a spheroidized ratio of cementite: 80% or more; and an average diameter of cementite: 0.3 µm to 2.2 µm, wherein a coefficient of micro-friction of ferrite on a surface of the steel sheet is less than 0.5.
