Monel 400 Fastener
Monel 400 is a Nickel-Copper alloy, resistant to sea water and steam at high temperatures as well as to salt and caustic solutions.Monel 400 is a nickel-copper alloy with excellent corrosion resistance in a wide variety of media. Monel 400 is characterized by good general corrosion resistance, good weldability and moderate to high strength.
The alloy has been used in a variety of applications. It has excellent resistance to rapidly flowing brackish water or seawater. It is particularly resistant to hydrochloric and hydrofluoric acids when they are de-aerated. The alloy is slightly magnetic at room temperature. Monel 400 is widely used in the chemical, oil and marine industries.

Monel 400 Features
Nickel Alloy 400/ Monel 400 Bolts and Nuts and Nuts
A nickel-copper alloy, Monel 400 bolts are a solid solution nickel alloy that can only be hardened by cold working. Best known for its corrosion resistance to reducing media and seawater, Monel 400 is also tougher in oxidizing environments than copper alloys. Also known as alloy 400, Monel 400 bolts are also utilized in high temperature, caustic and salt solution applications.High and Low Temperature Properties
Used for high temperature applications up to 1000°F in oxidizing atmospheres, Monel 400 bolts can also be used at higher temperatures if in a reducing environment. Though commonly used at high temperatures, Monel 400 bolts also retain their mechanical properties at subzero temperatures. Increased hardness at freezing temperatures has been shown to only slightly impair the ductility or impact resistance of Monel 400 bolts. Even when cooled to the temperature of liquid hydrogen, Monel 400 does not undergo a ductile-to-brittle transition which can cause fractures. This is especially unique compared to most ferrous materials which are often stronger, yet very brittle at extreme lowRenowned Seawater Resistance
Perhaps the best attribute of Monel 400 bolts is their ability to defy seawater corrosion. Uniquely, they offer resistance to rapidly moving seawater, which can erode other materials, though stagnant salt water situations can sometimes result in crevice and pitting corrosion. In addition, Monel 400 bolts prevent stress corrosion cracking and pitting in most fresh and industrial waters.General Corrosion Protection
Though it is best known for its resistance to sea water, Monel 400 bolts also show good resistance reducing media. It also resists oxidizing media better than many alloys with higher copper content. When it comes to acids, Monel 400 bolts offer very good protection from hydrofluoric acid in all concentrations up to the boiling point, as well as decent protection to sulfuric and hydrochloric acids under reducing conditions.Typical Mechanical Properties
