Nickel-based alloys containing optimum amount of chromium (Cr) molybdenum (Mo) and tungsten (W) are widely used in the chemical process industries due to their tolerance to both oxidizing and reducing conditions. Surprisingly most of the corrosion data available in literature for the corrosion-resistant alloys (CRA’s) are in individual acids which seldom replicate the field conditions. Although it is not feasible to exactly reproduce the field environment in a laboratory set-up but a better approach to understand the materials performance in field can be by conducting the corrosion tests in both individual and mixed acids.One of the most commonly used technique by industrial researchers to determine an alloy corrosion performance in a corrosive environment is weight change measurement method. In the present study corrosion tests were conducted using weight loss and electrochemical techniques for B-3 (UNS N10675) HYBRID-BC1 (UNS N10362) C-276 (UNS N10276) C-22 (UNS N06022) and C-2000 (UNS N06200) alloys in hydrochloric (HCl) sulfuric (H2SO4) nitric (HNO3) acids and their various combinations. For the comparative purposes corrosion tests were also conducted for 304L SS (UNS S30403) and 316L SS (UNS S31603) alloys in few of the above-mentioned acidic media. Further an attempt was made to correlate the corrosion performance of various alloys in individual and mixed acids based on the amount of their alloying elements.

Keywods: Ni-Cr-Mo Alloys, Ni-Cr-Mo-W Alloys, Stainless Steel, Hydrochloric Acid, Sulfuric Acid, Nitric Acid, Mixed Acids, Iso-Corrosion Curve, Potentiodynamic Polarization Technique

Sulfuric acid is one of the most important elementary substances of the chemical industry.  There is no stainless steel or even a nickel base alloy available which is suitable over the entire concentration range.  This paper will give corrosion data in up to 75 % sulfuric acid at boiling temperature for various commercial grades as well as for some new developmental alloys.
