The influence of a combined process, involving air cooling and heat treatment at 300 ℃, on precipitation behavior and corrosion resistance of a S31254-Ce steel was explored through scanning electron microscopy (SEM), energy dispersive X-ray spectrometry (EDS), electron backscatter diffraction (EBSD) and electrochemical analysis. After air cooling and heat treatment at 300 ℃, the S31254-Ce steel was conducive to the enrichment of Ce along the grain boundary and the content of Σ3 twins in aged samples increased. The composite heat treatment process is beneficial to inhibit the precipitation of precipitates in the aging process and improve the corrosion resistance of S31254-Ce steel.
