Inconel 825 is a titanium-stabilized nickel-chromium-iron-molybdenum-copper alloy designed for use in extremely corrosive environments. It has a very high resistance to oxidation and outstanding resistance to stress corrosion cracking in chloride conditions.
It is resistant to pitting corrosion in sulphuric and phosphoric acids and resists attack in strongly oxidising media such as nitrates, nitric acid and oxidising salts. It also resists most organic acids and alkali solutions. The alloy is reasonably ductile and can be worked in a similar way to austenitic stainless steels.
