UNS N08028, also known as Alloy 28, is a superaustenitic nickel-iron-chromium-molybdenum alloy designed to deliver outstanding resistance against a wide range of corrosive environments. It performs exceptionally well in conditions containing chlorides, sulfuric acid, and phosphoric acid, where conventional steels may fail. With its high alloy content, Alloy 28 combines excellent corrosion protection with reliable mechanical strength. This makes it a trusted choice for demanding applications.
Alloy 28 is used in environments where both corrosion resistance and mechanical reliability are essential. Its ability to withstand acids, chlorides, and other aggressive media makes it a dependable material for piping systems, heat exchangers, and process equipment exposed to harsh chemical or sour gas conditions.
