Monel R405 Description
Monel R405 (UNS N04405 / W.Nr. 2.4360, 2.4361 the free-machining version of Monel 400. A controlled amount of sulfur is added to the alloy to provide sulfide inclusions that act as chip breakers during machining. A Ni-Cu alloy with high strength and excellent resistance to a range of media including seawater, hydrofluoric and sulfuric acids, and alkalies. Used in marine and offshore engineering, chemical andhydrocarbon processing equipement, valves, pumps, shafts, fittings, fasteners, and heat exchangers.
Monel R405 Features
Resistant to seawater and steam at high temperatures
Excellent resistance to rapidly flowing brackish water or seawater
Excellent resistance to stress corrosion cracking in most freshwaters
Particularly resistant to hydrochloric and hydrofluoric acids when they are de-aerated
Offers some resistance to hydrochloric and sulfuric acids at modest temperatures and concentrations, but is seldom the material of choice for these acids
Excellent resistance to neutral and alkaline salt
Resistance to chloride induced stress corrosion cracking
Good mechanical properties from sub-zero temperatures up to 1020° F
High resistance to alkalis
