Product Description and Application

Monel 400(UNS N04400, NCu30) alloy is a high-strength single-phase solid solution, which is a kind of corrosion-resistant alloy with the largest amount, the widest use and excellent comprehensive performance. The alloy has excellent corrosion resistance in hydrofluoric acid and fluorine gas medium, and also has excellent corrosion resistance to hot concentrated alkali. At the same time, it is also resistant to corrosion of neutral solution, water, sea water, atmosphere, organic compounds, etc. An important feature of this alloy is that it generally does not produce stress corrosion cracking and has good cutting performance.

Monel 400 alloy is a copper-nickel alloy with excellent corrosion resistance, good corrosion resistance in various media, good welding performance, high strength and moderate, the alloy has been widely used in a variety of occasions, in salt water or seawater has excellent resistance to pitting corrosion, stress corrosion resistance. Especially resistant to hydrofluoric acid and hydrochloric acid. Widely used in chemical, petroleum, marine industry. Suitable for various corrosive environments, resistant to chloride ion stress corrosion cracking, and has good strength and toughness in a certain temperature range.
