Material Notes:

Carlson C20 Plus is a super-austenitic alloy, developed to provide maximum resistance to corrosion by sulfuric acid. Nickel chromium, molybdenum and copper contribute to the excellent overall resistance of C 20 Plus to chloride stress corrosion cracking and general pitting. Because this alloy is stabilized with columbium, it can be used in the as-welded condition, thus expediting on-site fabrication.ApplicationsAlthough C 20 Plus was developed primarily for sulfuric acid applications, it is also widely used in other chemical processing environments. C 20 Plus is employed in flue-gas scrubbers, sulfuric acid pickling, and in various other industries such as petroleum refining, pulp and paper, food and dyes.Chemical Processing – sulfuric acid, phosphoric acid, pesticides, formic and nitric acids, butadiene (synthetic rubber), caustics, solvents, explosives.Petroleum Refining.Flue Gas Scrubbing SystemsPulp and PaperFood and Dye ProcessingSulfuric Acid Pickling Equipment.Information provided by Carlson
