Nickel Alloys Alloy 400 Industrial Valves Overview
Zeon Exports supplies Nickel Alloy 400 (Monel, UNS N04400) industrial valves – ball, gate, globe and check types – a nickel-copper alloy with outstanding resistance to seawater, hydrofluoric acid and alkaline solutions for marine and chemical process lines.
Nickel Alloy 400 (Monel) Industrial Valves control and isolate flow in seawater, brine and acidic process streams in marine and chemical systems where standard stainless steels fall short. Its nickel-copper composition, with minimum 63% nickel plus cobalt and 28-34% copper, resists seawater, hydrofluoric acid, deaerated hydrochloric acid, alkaline solutions and steam across a wide temperature range.
- Minimum 63% nickel plus copper for outstanding seawater resistance
- Essentially non-magnetic in the annealed condition
- EN 10204 3.1 certified, export-ready worldwide

Corrosion Resistance of Nickel Alloys Alloy 400
Nickel Alloy 400 Industrial Valves offer a corrosion profile distinct from stainless steels, built around resistance to reducing rather than oxidizing media.
- Seawater resistance: excellent resistance to seawater and marine atmospheres, widely used in shipbuilding and offshore hardware.
- Acid resistance: strong resistance to hydrofluoric acid and deaerated hydrochloric acid.
- Alkali resistance: performs well in caustic soda and other alkaline process streams.
Heat Resistance of Nickel Alloys Alloy 400
Nickel Alloy 400 valves maintain good mechanical properties from sub-zero temperatures up to roughly 538°C (1,000°F). Strength decreases progressively above this range. Confirm exact service limits against the governing standard and application before specifying.
Key Properties of Nickel Alloys Alloy 400 Industrial Valves
Beyond corrosion and heat performance, Alloy 400 valves offer these additional properties.
- Good weldability using ERNiCu-7 (Monel 60) matching filler metal
- Strengthened by cold working, not heat treatment
- Good machinability compared to other nickel alloys
- Good toughness maintained into cold service temperatures
