Corrosion resistance of Incoloy 825
825 alloy is a general-purpose engineering alloy with high acid and alkali corrosion resistance in both oxidizing and reducing environments. Nickel composition makes the alloy effective in stress corrosion cracking resistance. Corrosion resistance is good in various media such as sulfuric acid, phosphoric acid, nitric acid and organic acids, alkali metals such as sodium hydroxide, potassium hydroxide and hydrochloric acid. The higher overall performance of Alloy 825 is manifested in a variety of nuclear combustion dissolvers with corrosive media such as sulfuric acid, nitric acid and sodium hydroxide.
