Abstract

In this paper, corrosion behaviors of 13MnNiMoR steel and its weld joint in the EO reactor service environment were studied. Metallographic analysis and electrochemistry corrosion tests in boiler water which are concerned on different zone metal of 13MnNiMoR steel weld joint have been carried out, and the effect of postweld heat treatment and the pH value of the working medium were discussed. The results indicated that the resistance of different zone metal in joint is tightly connected with their microstructure and heat-affected zone always shows the max corrosion current density. The results also showed that heat treatment could significantly improve the anticorrosion properties of 13MnNiMoR steel weld joint.
