Abstract: A method for producing steel includes: (a) a step of adding the first group of alloys to molten steel having an amount of dissolved oxygen of 0.0050 mass % or more; (b) a step of, after the step of (a), adding deoxidizer to the molten steel for deoxidation; (c) a step of, after the step of (b), adding the second group of alloys to the deoxidized molten steel; and (d) a step of, after the step of (c), adding REM to the molten steel, wherein amounts of oxygen Ob introduced from the first group of alloys (mass %) and amounts of oxygen Oa introduced from the second group of alloys (mass %) satisfy [Oa?0.00100], [Ob+Oa?0.00150], and [Ob/Oa?2.0], and satisfy a formula [0.05?REM/T.O?0.5] after the step of (d).
