摘要： .epsilon. phase precipitates in the matrix having a composition of 0.07% or less carbon, 1 or less silicon, 1% or less manganese, 2.5 to 5% copper, 3 to 5.5% nickel, 14 to 17.5% chromium, 0.5% or less molybdenum, 0.15 to 0.45% niobium, by weight, and the balance composed substantially of iron, and comprising 6 to 30 vol % austenitic phase and the balance composed substantially of martensitic phase. In a method of producing a structural member in which first solution treatment is performed at 1010.degree. to 1050.degree. C. on a stainless steel having a composition described above and first aging treatment is performed at a temperature not lower than 520.degree. C. and not higher than 630.degree. C., second solution treatment is performed at 730.degree. to 840.degree. C., and then second aging treatment is performed at a temperature not lower than 520.degree. C. and not higher than 630.degree. C. or a structural member of any shape is fabricated by means of welding work before the second solution treatment. Also, a structural member is produced by performing first solution treatment at 1010.degree. to 1050.degree. C. on a stainless steel having a composition described above, performing aging treatment at a temperature not lower than 520.degree. C. and not higher than 630.degree. C., fabricating a structural member of any shape by means of welding work, heating the material at a rate of 100.degree. C./hour or lower, performing second solution treatment at 1010.degree. to 1050.degree. C., cooling the material in a furnace to room temperature at a cooling rate of 100.degree.
