Abstract

Abstract: Solution treatment was performed at 1080 ℃ for S32205 duplex stainless steel welded joint welded with multi-stranded wire, and the effect of which on microstructure, mechanical properties and pitting corrosion resistance of the welded joint was analyzed by means of electronic backscatter diffraction, scanning electron microscope, electronic universal test machine and electrochemical test. The results show that after solution treatment at 1080 ℃, the main alloying elements of the welded joint are fully diffused, the microstructure is more uniform, the austenite volume fraction of the weld is increased by 11.2%, and the ratio of ferrite and austenite is more balanced. After the solution treatment, the average tensile strength of the welded joints increases by 32.7 MPa, the plasticity improves slightly, and at the same time, the pitting corrosion resistance of the welded joints is significantly improved.

Key words: solution treatment, S32205 duplex stainless steel, welded joint, mechanical properties, pitting corrosion resistance
