Product Description

Product Description
Introduction 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 when they are de-aerated. As would be expected from its high copper content, alloy R-405 is rapidly attacked by acid and ammonia systems.
Composition The chemical composition of stainless steel grade Monel R405 is outlined in the following table.

Characteristic
Characteristics are essentially the same as those of Monel 400 such as:
Good machinability and is recommended for use with automatic screw machines 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 when they are de-aerated Offers some resistance to hydrochloric and sulfuric acids a 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 High resistance to alkalis
