Incoloy 825 UNS N08825 Sheet / Bar / Foring Ring

Common Trade Names: Incoloy 825, Alloy 825, Nickel 825, UNS NO8825, W.N r.2.4858 , NiFe30Cr21Mo3

The high nickel content gives the alloy effective stress corrosion cracking resistance.
Corrosion resistance is good in a variety of media, such as sulfuric, phosphoric, nitric and organic acids, alkali metals such as sodium hydroxide, potassium hydroxide and hydrochloric acid solutions.
The higher overall performance of Incoloy 825 is shown in a nuclear combustion dissolver with a variety of corrosive media, such as sulfuric acid, nitric acid and sodium hydroxide, all processed in the same equipment.

Why Incoloy 825 ?

 825 alloy is a kind of general engineering alloy, which has the acid and alkali corrosion resistance in oxidation and reduction environment and effective resistance to stress corrosion cracking for its high nickel composition.In all sorts of media, corrosion resistance is very good such as sulfuric acid, phosphoric acid, nitric acid and organic acid, to alkali, such as sodium hvdroxide, potassium hvdroxide and hvdrochloric acid solution. The higher comprehensive performance of 825 alloy shows in nuclear burning dissolver of various corrosion medium, such as sulfuric acid, nitric acid and sodium hvdroxide are all handled in the same equipment.

• Good resistance to stress corosion cracking.
• Good resistance to pitting and crevice corrosion
• Good resistance to oxidization and non oxidizing acid.
• Good mechanical properties at room temperature or up to550℃
• A certification of manufacturing pressure vessel of 450 ℃

Incoloy 825 Application field:

Components such as heating coils, tanks, crates, baskets and chains in sulphuric acid pickling plants

Sea-water-cooled heat exchangers, offshore product piping systems; tubes and components in sour gas service
