| description | A tubular component for a pressurised-water nuclear reactor, has the following composition by weight:0.8%≤Nb≤2.8%;traces≤Sn≤0.65%;0.015%≤Fe≤0.40%; preferably 0.020%≤Fe≤0.35%;traces≤C≤100 ppm;600 ppm≤O≤2300 ppm; preferably 900 ppm≤O≤1800 ppm;5 ppm≤S≤100 ppm; preferably 8 ppm≤S≤35 ppm;traces≤Cr+V+Mo+Cu≤0.35%;traces≤Hf≤100 ppm;F≤1 ppm;the remainder being zirconium and impurities resulting from production. The tubular component has an outer surface with a roughness Ra less than or equal to 0.5 μm, obtained following a final mechanical polishing step. The outer surface has a roughness Rsk≤1 in absolute value and a roughness Rku≤10. |
