Method for producing abrasion-resistant steel having excellent surface property

A method for producing an abrasion-resistant steel having excellent surface property comprising the steps of:

• preparing a molten steel consisting essentially of 0.1 to 0.45 wt. % C, 0.1 to 1 wt. % Si, 0.1 to 2 wt. % Mn, 0.04 wt. % or less P, 0.04 wt. % or less S, 0.1 to 1 wt. % Ti, 0.0015 to 0.01 wt. % N, and the balance being Fe and inevitable impurities, said steel having Ti* of 0.05 wt. % or more and less than 0.4 wt. %, said Ti* being specified by equations of;
• Ti*=Ti(a)-[Ti],
• Ti(a)=Ti-{(48/14)N+(48/32)S},
• log[Ti][C]=(-10580/T)+4.38,
• [Ti]=4.times.[C]+{Ti(a)-4.times.C},
• where log[Ti][C]=(-10580/T)+4.38 is an equation designating the temperature dependency of solubility product of TiC, [Ti] designates wt. % of Ti at an equilibrium solubility, [C] designates wt. % of C at an equilibrium solubility, T designates an absolute temperature, and Ti, N, S, and C designate wt. % of a respective element in the steel;
• casting continuously said molten steel to produce slab, coarse particles of TiC being precipitated in the slab;
• hot-working the slab to produce a hot-rolled steel sheet at 1300.degree. C. or less;
• and
• quenching the hot-rolled steel sheet.
