Sulfuric and hydrochloric acids are among the most common chemicals produced and used in the further production of other chemicals in the process industry. By themselves these acids are very corrosive but also the presence of impurities can further complicate corrosion reactions. The use of nickel alloys have been a traditional material of choice for handling these corrosive acids. Of course economical considerations also play a part and they key is to use an alloy suffienct for the service while avoiding over-designing so that equipment costs are kept under check. This paper will review the various alloys available for use in this service as well as identify the temperature limits and other conditions that should be considered when selecting an alloy.

Keywords: Sulfuric acid, hydrochloric acid, nickel alloy, oxidizers, UNS N06059, UNS N08031, chemical process equipment
