904L valves for Corrosive Petrochemical Applications

904L valves made of UNS N08904

Looking for a valve in this exotic alloy? Find it in the following configurations: Ball, Butterfly, Cast, Check, Control, Cryogenic, Custom made, Foot, Forged, Gate, Globe, Needle, Plug, and Safety relief, as well as Strainers.

The Alloy Valve Stockist supplies 904L gate valves and N08904 globe valves. Our check valves are particularly suited for sulphuric acid, and we stock ball valves for acetic acid service, as well as butterfly, plug, needle and custom made valves for phosphoric acid conditions. Although originally developed for its resistance to sulphuric acid, 904L also has a very high resistance to a wide range of environments. Although originally developed for its resistance to sulphuric acid it also has a very high resistance to a wide range of environments. The material has good resistance to warm sea water. High nickel (Ni) content results in a much better resistance to stress corrosion cracking than the standard austenitic grades.

With excellent weldability and formability 904L also maintain non-magnetic state in all conditions.904L provides excellent toughness , even down to cryogenic temperatures with its austenitic structure.
