Incoloy825

Incoloy 825 is a titanium stabilized all austenitic nickel-iron-chromium alloy with copper and molybdenum additions.Incoloy 825 is a versatile engineering alloy with resistance to acid and alkali metal corrosion in both oxidizing and reducing environments.

The high nickel content gives Incoloy 825 alloy an effective resistance to stress corrosion cracking. The corrosion resistance is excellent in a variety of media such as sulfuric, phosphoric, nitric and organic acids, alkali metals such as sodium hydroxide, potassium hydroxide and hydrochloric acid solutions. the higher overall performance of Incoloy 825 is demonstrated by the diversity of corrosive media in nuclear combustion dissolvers such as sulfuric acid, nitric acid and sodium hydroxide all handled in the same equipment.
