ASTM B564 Monel 400 N04400 Nickel Alloy Flange B16.5 FF RF RTJ
Monel 400 Flanges 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.
The functionality of the Astm B564 Monel Pipe Flange is so great that its mechanical properties remain unaffected despite exposure to a temperature as high as 1000° F.
