PROBLEM TO BE SOLVED: To provide an Fe-based powder-densely-solidified molding excellent in oxidation resistance and high temperature strength.SOLUTION: The Fe-based powder-densely-solidified molding excellent in high temperature strength and creep strength is provided that is a ferritic stainless steel containing, by mass%, Cr:9 to 30%, Al:1 to 10%, Si:0.05 to 1.0%, N:0.01 to 0.20% and further one or two kind of Zr and Hf of 0.01 to 0.50% in total and the balance Fe with inevitable impurities. The Fe-based powder-densely-solidified molding is characterized in that 30 or more of fine nitride of 1 μm or less are dispersed in 400 μm square in ferrite structure.SELECTED DRAWING: Figure 2 |
