Alpha Overseas is an acknowledged exporter and offers a wide range of Monel 400 Flanges, which is particularly resistant to hydrochloric and hydrofluoric acids when they are de-aerated. As would be expected from its high copper content, Monel 400 Pipe Flanges is rapidly attacked by nitric acid and ammonia systems. Monel Alloy 400 Flanges contains the same quantity of nickel and copper as is found in a naturally occurring nickel ore. Nickel Alloy 400 Flanges is a group of nickel alloys, primarily composed of nickel and copper, with small amounts of carbon, silicon, iron and manganese. The conventional machining techniques used on iron alloys may be used for Monel Alloy 400 Pipe Flanges, where further it has good ductility and thermal conductivity.

Resistant to both seawater and steam, the anti-corrosive and toughness properties of Nickel Alloy 400 Pipe Flanges make it perfect for heavy duty applications such as transfer (pipe) piping used in oil refineries. Monel UNS N04400 Flanges is often used in fresh water and gasoline tanks; crude petroleum stills, piping and process vessels; boiler feed-water heaters and other related heat exchangers; deaerating heaters and so on.

Exceptional resistance of Monel Din 2.4360 Flanges has been proven in hydrofluoric acid in all concentrations up to the boiling point. Monel Din 2.4361 Flanges has great mechanical properties at sub-zero temperatures, and can be used in temperatures up to 1000 Degree F, where its melting point is 2370 Degree F – 2460 Degree F.
