Monel r405
Details
Lork Group high-quality Monel R405 is a solid solution alloy that can only be hardened by cold working. Monel R405 exhibits characteristics like good corrosion resistance, good weldability, and high strength.
Products Description
Lork Group's high-quality 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 seawater 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 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.

Characteristics of Monel R405
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 and hydrofluoric acids 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
Monel R405 Application
Alloy R-405 is chiefly used for automatic-screw-machine stock and it not generally recommended for other applications. Screw machine stock for fasteners and similar high production run items.
Meter and valve parts
Fasteners
