The molten steel is then cast into a steel stock. The steel stock is thereafter heated at 1,050 to 1,200°C, subsequently subjected to hot rolling where the cumulative draft in the temperature range of Ar 3 to (Ar 3 +100°C) is ≥35%. Next, cooling at a mean cooling rate of ≥2°C/s is applied to the temperature range of ≤450°C.
