Product Description

Monel Pipe

Monel Alloy 400 is a nickel-copper alloy resistant to seawater and steam at high temperatures and widely used in the chemical, oil and marine industries. As a solution strengthened material, it displays good strength, toughness and corrosion resistance at temperatures up to 400°C.

Its corrosion resistance is particular strong in rapid flowing brackish water or seawater. Alloy 400 also exhibits good resistance to hydrofluoric and dilute non-oxidising acids, alkalis and salts. It also resists corrosion by dry chlorine and hydrogen chloride and is not susceptible to stress corrosion cracking. This grade is readily cold formable and weldable.
