The invention creep performance relates to improved reactor core Component high chromium ferritic / martensitic steel, and a method of manufacturing for, 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.%, chromium 8.5 ~ 9.5 wt%, molybdenum 0.45 ~ 0.55 wt%, vanadium 0.10 ~ 0.25% by weight, tantalum 0.02 ~ 0.10%, niobium 0.21 ~ 0.25 wt%, tungsten 1.5 to 3.0% by weight, a nitrogen 0.015 ~ 0.025 wt%, boron 0.01 ~ 0.02% by weight and parts made of iron glass, to a high chromium ferritic / martensitic steel, and a method of manufacturing, characterized in that does not contain cobalt. High chromium ferritic / martensitic steel according to the invention may in particular be useful to the fourth generation SFR nuclear fuel materials for use in high temperature and high neutron irradiation conditions so to optimize the nitrogen and boron contents exhibited excellent tensile strength and creep performance is.
