NO8825 {825} is the full titanium stabilized austenitic chromium-nickel-iron alloy, and added copper and molybdenum. 825 is a universal engineering alloys, the oxidation and reduction conditions have acid and alkali metal corrosion. High nickel composition of the alloy with effective anti-stress corrosion cracking. In various media are very good corrosion resistance, such as sulfuric acid, phosphoric acid, nitric acid and organic acid, alkali metal such as sodium hydroxide, potassium hydroxide and hydrochloric acid. 825 higher overall performance in a variety of corrosive media in the nuclear burning dissolver, such as sulfuric acid, nitric acid and sodium hydroxide are handled in the same device.

NO8825 {825} alloy characteristics:

     ● good resistance to stress corrosion cracking
