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

Monel R405 Applications：
