Abstract
The oxide film thickness of the steel material surface (d+d) is made to become 15 nm or less where post-treatment after water-cooling is not needed by suitably setting the conditions of the water-cooling start temperature (T), water-cooling end temperature (T), steel material thickness (d), concentration of solute oxygen in the cooling water (D), and cooling rate (C) in the equation of d+d=7.98×10(T−T)dD+{5.50×10(T−T)−6.51(T−T)}/C.
