Abstract:

An economical nickel-saving casting duplex stainless steel (DSS) Cr25Mn10Mo4Ni2N was melted in a mid-frequency induction furnace. The effect of solution temperature on microstructure and corrosion resistance property of the DSS were studied by means of optical microscope(OM), X-ray diffraction(XRD), scanning electron microscopy(SEM) and electrochemical workstation. The results indicate that the microstructure consists of α, γ and σ phases for the steel solution-treated at temperatures of 1000 to 1100 . With increasing solution temperature, the morphology of σ phase changes from fine island into thick one. As the solution temperature is increased to 1120 , the σ phase completely disappears, and the microstructure only contains α and γ phases. After solution-treated at 1120 , the steel has the lowest corrosion current density and the largest charge transfer resistance in artificial seawater, which shows it has excellent pitting corrosion resistance. At the temperature of 1150 , its pitting corrosion resistance is poorer. When the solid-solution temperature is increased from 1000 to 1100 , its pitting corrosion resistance of the steel is improved.
