Corrosion Resistance:Incoloy 825 alloy is a universal engineering alloy with high resistance to acid and alkali metal corrosion in both oxidizing and reducing environments due to its high nickel content, making the alloy effectively resistant to stress corrosion cracking. It exhibits excellent corrosion resistance in various media such as sulfuric acid, phosphoric acid, nitric acid, and organic acids, as well as alkali metals such as sodium hydroxide, potassium hydroxide, and hydrochloric acid solutions. The superior comprehensive performance of alloy 825 is demonstrated in nuclear fuel dissolvers with diverse corrosion media such as sulfuric acid, nitric acid, and sodium hydroxide all handled in the same equipment. Incoloy 825 alloy is resistant to boiling sulfuric acid concentrations up to 40% and all concentrations of sulfuric acid at temperatures below 80°C and 66°C. Regarding phosphoric acid and others, INCOLOY 825 exhibits excellent corrosion resistance. It also shows good resistance to pitting in solutions containing chlorides, stress corrosion, and intergranular corrosion.

Applications:Sulfuric acid pickling equipment, phosphoric acid production equipment, petrochemical equipment, coal chemical industry, marine platforms, seawater desalination, composite plates, bellows expansion joints, and other industries and products.
