Exploring heat treatment on the corrosion resistance of SA106B tubes in high temperature pressurized water with different flow velocities
Source abstract
Abstract
The SA106B carbon steel was widely used for the pipeline in pressurized water reactor and suffered from severe high temperature corrosion. In this work, we expected to improve its corrosion resistance through simple heat treatment. The results showed that the tubes after the treatment normalized at 920 ℃ for 20 min and subsequently cooled in air displayed the best corrosion resistance due to the elimination of banded ferrite/pearlite structure, the reduction in the area ratio of anode/cathode and the decrease in grain size. In addition, the oxidation process and the effect of flow velocity were also discussed in detail.
