After such a steel pipe material is formed into a steel pipe, the steel pipe is quenched by cooling after heating to a temperature of the AC3 transformation point or more and tempered at a temperature of the AC1 transformation point or less. The composition may further contain at least one element of Nb and Ti; at least one element selected from the group consisting of Zr, B, and W; or Ca, singly or in combination. Preferably, the steel pipe has a martensitic structure containing 5 to 25 percent by volume of a residual austenite phase, or further containing 5% percent by volume or less of a ferrite phase. Thus, the resulting stainless steel pipe for oil country tubular goods exhibits a superior corrosion resistance even in extremely severe, corrosive environments containing carbon dioxide gas (CO2), chloride ions (Cl−), or the like.
