ASTM B165 UNS N04400, Monel 400, 2.4360 Nickel Copper Alloy Steel

ASTM B165 UNS N04400， Monel 400， 2.4360 Nickel Copper Alloy Steel

蒙乃尔 400 is a nickel-copper alloy (about 67% Ni – 23% Cu) that is resistant to sea water and steam at high temperatures as well as to salt and caustic solutions. Alloy 400 is a solid solution alloy that can only be hardened by cold working. This nickel alloy exhibits characteristics like good corrosion resistance， good weldability and high strength. A low corrosion rate in rapidly flowing brackish or seawater combined with excellent resistance to stress-corrosion cracking in most freshwaters， and its resistance to a variety of corrosive conditions led to its wide use in marine applications and other non-oxidizing chloride solutions. This nickel alloy is particularly resistant to hydrochloric and hydrofluoric acids when they are de-aerated. As would be expected from its high copper content， alloy 400 is rapidly attacked by nitric acid and ammonia systems.

A solid solution alloy， 蒙乃尔 400 is an alloy that exhibits superior resistance to the marine environment. This is an alloy which can only be strengthened by cold working. Cold worked Alloy 400 Pipe produced under specification ASTM B165， is available in both a seamless or welded construction. Nickel based ASME SB 165 UNS N04400 exhibits a lower rate of corrosion in rapidly flowing brackish/saline water or seawater as well as steam at elevated temperatures. In the presence of caustic solutions， the resilience of a Monel Pipe is amazing. Furthermore， the display of excellent corrosion resistance properties makes this alloy grade well suited for applications in several freshwater sources. Hence， 蒙乃尔 400 管 is used in chemical processing and marine environments.

The corrosion resistance to acids such as hydrochloric acid or hydrofluoric acid in a deaerated condition， of the 蒙乃尔 400 is what makes them suitable for use in non-oxidizing chloride based solutions. In an annealed condition， the strength of a Monel 400 EFW Pipe is relatively low. This can be remedied by the use of various tempers， which can result in an increase in strength. The Monel 400 Welded Pipe can be used at temperatures as high as about 1000° F down to cryogenic temperatures. Apart from having good resistance to alkalis， the ASTM B725 UNS N04400 demonstrates excellent resistance when exposed to solutions containing neutral and alkaline salts.
