==Original Abstract Submitted==

A duplex stainless steel material that has excellent general corrosion resistance and pitting resistance in a supercritical corrosive environment in which SOgas and Ogas are contained in a supercritical COgas is provided. A duplex stainless steel material of the present disclosure has the chemical composition described in the description, and in the duplex stainless steel material, on a precondition that the content of each element is within a range described in the description, Fn defined by Formula (1) is 44.0 or more, and a total number per 1 mmof Mn sulfides having an equivalent circular diameter of 1.0 μm or more and Ca sulfides having an equivalent circular diameter of 2.0 μm or more is 0.50/mmor less.
