Provided is a Fe-based powder-densely-solidified molding having excellent high-temperature strength and excellent creep strength. This Fe-based powder-densely-solidified molding is a ferrite-type stainless steel which comprises, in mass%, 9-30% of Cr, 1-10% of Al, 0.05-1.0% of Si, 0.01-0.20% of N, at least one element selected from Zr, Ti, Hf, Re and Y in the total amount of 0-0.50%, and a remainder made up by Fe and unavoidable impurities. In a ferrite structure, a fine nitride having a size of 1 mum or less is dispersed at a density of 30 particles or more per 400-mum square. |
