Alloy 20 bars are commonly used in applications such as chemical processing, food processing, pharmaceuticals, and more.Alloy 20 exhibits exceptional corrosion resistance, particularly in sulfuric acid environments. It also resists corrosion by phosphoric acid, nitric acid, and chloride-containing media.The typical chemical composition of Alloy 20 includes nickel, chromium, iron, copper, and small amounts of other elements such as molybdenum and niobium.
