The solid solution UNS N08810 alloy was stabilized under different stabilization regimes.According to relevant standards,mechanical properties,intergranular corrosion tests were carried out on the specimens in different states.The effects of different stabilization processes on the mechanical properties and corrosion properties of UNS N08810 alloy were studied.The results show that when the heat treatment process is as follows:the heating rate from 400℃ to 899℃ with a rise rate≥150℃/h,the heat holding rate at 899℃ for 5 hours,and the cooling rate at 80～150℃/h to 400℃,after being air-cooled,the precipitated phase content on the grain boundary of UNS N08810 is lower than that on the grain boundary after other stabilization treatments,making UNS N08810 have the best corrosion resistance and good mechanical properties.
