STAINLESS STEEL PIPE AND METHOD FOR MANUFACTURING THE SAME

Provided are a stainless steel pipe and a method for manufacturing the same. The stainless steel pipe has a chemical composition containing, by mass %, C: 0.05% or less, Si: 1.0% or less, Mn: 0.10% to 2.0%, P: 0.05% or less, S: less than 0.005%, Cr: 16.0% to 20.0%, Mo: 0.6% to 1.4%, Ni: 3.0% to 5.0%, Al: 0.001% to 0.10%, N: 0.010% to 0.100%, O: 0.01% or less, Cu: 0.3% to 3.5%, and a balance of Fe and incidental impurities, in which predetermined relational expressions are satisfied by Cr, Ni, Mo, W, Cu, and C, a microstructure including, in terms of volume fraction, 45% or more of a tempered martensitic phase, 20% to 40% of a ferrite phase, and 5% to 25% of a retained austenite phase, a yield strength of 758 MPa or higher, and an absorbed energy at a temperature of −10° C. vE−10 of 40 J or more.
