The present invention, specifically, carbon 0.04 ~ 0.13 wt%, silicon 0.03 ~ 0.07 wt%, manganese 0.40 ~ 0.50 wt%, nickel 0.40 ~ 0.50 wt on creep resistance is excellent high chromium ferritic / martensitic steel and a method for producing %, 8.5 ~ 9.5 wt% chromium, molybdenum, 0.45 ~ 0.55 wt%, vanadium 0.10 ~ 0.25% by weight, tantalum 0.02 ~ 0.10%, niobium 0.15 ~ 0.25 wt%, tungsten 1.5 to 3.0% by weight, and nitrogen 0.05 ~ 0.12 wt% boron 0.004 ~ 0.008 wt%, optionally phosphorus and zirconium are respectively 0.002 0.010 wt%, 0.01 to 0.08% by weight, remainder iron, and other high tensile strength and creep resistance, including unavoidable impurities, high chromium ferritic / martensitic steel, and It relates to a production method thereof. Exhibits a controlled in excellent tensile strength and creep resistance of the high chromium ferritic / martensitic steel is niobium, tantalum, tungsten, nitrogen, boron, and the content of alloy elements such as zirconium, carbon according to the present invention, in a high-temperature and high-dose conditions It can be effectively used as a fourth-generation SFR nuclear fuel material used.
