Beschreibung
Zusammenfassung:	An object of the present invention is to provide a stainless steel pipe which exhibits excellent corrosion resistance so as not to rust at an early stage even in a waterfront environment affected by sea salt particles. The stainless steel pipe has a polishing mark on a surface, an oxide film exhibiting color is not present on the surface, and an average number of surface defects including covering by a metal base of 5 µm or more on the surface is suppressed to 5 or fewer per 0.01 mm 2 .
