51317--9639-The Performance of Corrosion Resistant Ni-Cr-Mo Alloys in Concentrated Hydrochloric Acid

This paper is to study the corrosion performance of various Ni based alloys in high concentrations of HCl acids below the boiling point. Nickel-based alloys C-276 (UNS N10276), C-22 (UNS N06022), C-2000 (UNS N06200), Hybrid-BC1 (UNS N10362) and B-3 (UNS N10675) were investigated.

Wrought corrosion-resistant nickel alloys offer excellent resistance to hydrochloric acid. Of particular interest in this paper is the performance of various nickel-chromium-molybdenum and nickel-molybdenum alloys in concentrations >20% of hydrochloric acid below their boiling points. In this work the corrosion resistance of N06022 N06200 N10276 N10675 and N10362 was studied in solutions of 20-37% HCl. The goal of this test program is to identify conditions resulting in corrosion rates close to 0.5 mm/y the accepted maximum for industrial use.Based on the available data an attempt was made to draw iso-corrosion lines of 0.5 mm/y for selected alloys in the range 20 to 37% HCl. Additionally the corrosion performance of selected alloys (N10362 N06022 N06200 and N10675) was also studied by electrochemical polarization behavior.

Keywords: Nickel alloys, hydrochloric acid, heat treated, mill annealed, iso-corrosion lines
