Abstract The hot corrosion behavior in molten salt (75%Na2SO4+25%K2SO4) at 850 oC of Hastelloy X alloy made by additive manufacturing was studied, and then the room temperature mechanical properties of the alloy after molten salts corrosion were also assessed. The results show that the corrosion products of Hastelloy X are mainly composed of Ni-, Ti- and Cr-oxides. After hot corrosion for different times, the tensile strength of the additive manufactured alloy at room temperature changes little, while the rupture strength and plasticity decrease significantly, which may be ascribed to the change of the surface state and structure of the alloy induced by the molten salts corrosion process in terms of the effect of temperature and corrosion.
