Corrosion resistance:

Incoloy825 alloy is a general engineering alloy, which has acid and alkali corrosion resistance in oxidation and reduction environment. High nickel composition makes the alloy have effective stress corrosion cracking resistance. It has good corrosion resistance in various media, such as sulfuric acid, phosphoric acid, nitric acid and organic acids, and alkali metals such as sodium hydroxide, potassium hydroxide and hydrochloric acid solution. The high comprehensive performance of 825 alloy is shown in the Nuclear Combustion dissolver with various corrosive media, such as sulfuric acid, nitric acid and sodium hydroxide, which are all treated in the same equipment. Incoloy825 alloy is resistant to boiling sulfuric acid with a concentration of 40% and sulfuric acid with a concentration of 60% and a temperature within 80 ° C and 66 ° C. In terms of phosphoric acid, Incoloy 825 has very good corrosion resistance. It has good corrosion resistance to solutions containing chloride, pitting corrosion in seawater and stress corrosion. In addition, it also has good corrosion resistance to intergranular corrosion.
