The corrosiveness of sulfuric acid is strongly dependent upon acid concentrations and temperatures among other factors. Carbon steels stainless steels and Ni-base alloys exhibit acceptable corrosion rates in many applications involving sulfuric acid depending upon the concentration of the acid and the temperatures involved. At an acid concentration range of 70-95% Ni-base alloys may only provide acceptable corrosion rates at lower temperatures. At higher use temperatures such as 150 ?C (302 ?F) very limited corrosion data for Ni-base alloys is available in published literature. The present paper discusses the results of sulfuric acid corrosion testing at 150 ?C (302 ?F) in 80% H2SO4 for weld overlays of Ni-base alloys including Ni-Cr-Mo Ni-Cr-Fe and Ni-Mo alloys. .
