Abstract (en)
[origin: EP3115476A1] Specific amount of each of C, Si, Mn, P, S, Ni, Cr, Cu, Mo, Nb, Ti, B and N is contained, a specific amount of at least one of Mg and Ca is contained, a total of Nb and Ti is 0.3% or more, and the remainder is Fe and unavoidable impurities. A cumulative number density of a precipitate whose particle diameter falls within a range of more than 0 nm up to 100 nm is 0.1 to 2.0 Number/µm 2 , a precipitate particle diameter corresponding to a half of the cumulative number density in a distribution of the cumulative number density and the precipitate particle diameter is 70 nm or less, an average hardness is 160 Hv or less, and a grain size number is 7.5 or more.
