MONEL 400 & MONEL R405
MONEL® 400
MONEL® nickel-copper alloy 400 (UNS N04400/W.Nr. 2.4360 and 2.4361) is a solid-solution alloy that can be hardened only by cold working. It has high strength and toughness over a wide temperature range and excellent resistance to many corrosive environments.
Alloy 400 is widely used in many fields, especially marine and chemical processing. Typical applications are valves and pumps; pump and propeller shafts; marine fixtures and fasteners; electrical and electronic components; springs; chemical processing equipment; gasoline and fresh water tanks; crude petroleum stills, process vessels and piping; boiler feedwater heaters and other heat exchangers; and deaerating heaters.
Monel® R405 is the free machining version of the 400 Series. The added sulfur act as chip breakers during machining, providing excellent strength, corrosion resistance, and weldability. Monel® R405 is commonly utilized within marine applications and other non-oxidizing chlorine solutions.
There are three widely used Monel alloys, namely 400, R-405, and K-500. Monel 400 and R-405 are similar in mechanical properties, but R-405 is easier to machine because of its higher sulfur content. K-500 is specially formulated with aluminum and titanium additions to increase its mechanical strength. Monel 400 and R-405 can only be work hardened, whereas K-500 can be both work hardened and precipitation hardened.
