AMS 4674 is a specification for Monel R405 Bars & Forgings, Monel R405 (UNS N04405) is the free-machining grade of Monel 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.
Like Monel 400, Monel R405 bars is resistant to sea water and steam at high temperatures as well as to salt and caustic solutions. 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 steel alloy is particularly resistant to hydrochloric and hydrofluoric acids when they are de-aerated. As would be expected from its high copper content, alloy R-405 is rapidly attacked by nitric acid and ammonia systems.
In what forms is Monel R405 Available at Lork Group?
- Round Bar (ASTM specification B 164)
- Hex Bar
