High nickel content makes INCOLOY 825 alloy have effective stress corrosion cracking resistance. Corrosion resistance in various media is very good, such as sulfuric acid, phosphoric acid, nitric acid and organic acid, alkali metals such as sodium hydroxide, potassium hydroxide and hydrochloric acid solution. Incoloy 825 has higher comprehensive performance in Nuclear Combustion dissolvers with various corrosive media, such as sulphuric acid, nitric acid and sodium hydroxide, which are all treated in the same equipment.

Characteristics of Incoloy 825:
1. Good pitting corrosion resistance and crevice corrosion performance
2. Good oxidation resistance and non-oxidative thermal acid properties
3. Good mechanical properties at room temperature and high temperatures up to 550 ° C
4. Certification of pressure vessels with a manufacturing temperature of 450 ° C
