Product Description

Monel R405 UNS N04405 Resistant to Sea Water and Steam at High Temperatures



A-ONE ALLOY keeps in stock hot forged Monel R405 round bar and could make fast delivery for customized sizes.


Monel R405 is the free machining version of Monel 400. It is a nickel-copper alloy with a controlled amount of sulfur added to provide sulfide inclusions that act as chip breakers during machining. Like Monel 400, alloy R-405 is resistant to sea water and steam at high temperatures as well as to salt and caustic solutions. Monel R405 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 steel alloy is particularly resistant to hydrochloric and hydrofluoric acidswhenthey are de-aerated. As would be expected from its high copper content, alloy R-405 Monel R405 Hex Baris rapidly attacked by nitric acid and ammonia systems.
