Materials Performance in Oxidizing Acid and Corrosive Solution containing Oxidants

Nickel-based alloys containing optimum amounts of chromium (Cr) molybdenum (Mo) and tungsten (W) are widely used in the chemical process industries due to their tolerance of both oxidizing and reducing conditions. In the present study corrosion tests were performed using weight loss and electrochemical techniques for Ni-based CRAs in various corrosive solutions. The motivation of this study is to understand thematerials performance in oxidizing acid (such as nitric acid) and acidic solutions containingoxidants (like ferric ion cupric ion peroxide etc.). An attempt was further made to correlate the corrosion performance of the alloys in individual and mixed acids to their alloying elements and contents.The corrosion data suggest that in oxidizing acid reducing + oxidizing acid and in solutions containing oxidants HASTELLOY® G-35® (UNS N06035) (Ni-33Cr-8Mo) exhibits a remarkably high corrosion resistance than existing nickel and iron-based alloys.
