| Abstract: | The pickling process of 316L stainless steels was studied in the paper by means of orthogonal experiment. Polarization curve was used to measure pitting potential of base metal, heat - affected zone and weld area. The influence of pickling on pitting - resistance property was evaluated by it. Test results showed that the optimized pickling process could clean oxide skin of weld surface in effect and improve pitting - resistance property greatly. |
