Incoloy 825 Alloy Sheet

Incoloy 825 is a NI-FE-MO-CU corrosion-resistant alloy stabilized with Ti. The alloy has effective resistance to uniform corrosion and localized corrosion, and has good performance, so it is widely used in chemistry, energy, and hydrometallurgy. Application. In addition, the alloy has good toughness and performs well in the atmosphere. However, it should be noted that very shallow pitting corrosion will occur in humid atmosphere. This alloy is also resistant to freshwater corrosion and can be used in flowing seawater under all conditions. However, Spotting can occur in still seawater or under polluted conditions.
The high nickel content of Incoloy 825 gives the alloy effective resistance to stress corrosion cracking. It has good corrosion resistance 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 solution. The higher comprehensive performance of Incoloy 825 is demonstrated in nuclear combustion dissolvers with various corrosive media, such as sulfuric acid, nitric acid and sodium hydroxide, all processed in the same equipment.
