What Are Monel 400 Fasteners?
Monel 400 fasteners are fasteners made from Monel Alloy 400, a solid-solution nickel-copper alloy containing about 63% nickel and 28–34% copper. The alloy is resistant to corrosion in salt water environments, acidic environments, sea water environments and high temperature applications.
The unique metallurgical properties of Monel 400 Bolts and Nuts make them highly suitable for use in marine engineering, desalination plants, chemical processing plants, offshore platforms, heat exchangers and power generation equipment.
The alloy is known by several international designations including:
- UNS N04400 Fasteners
- Werkstoff Nr 2.4360 Bolts
- 2.4360 (Alloy 400) Bolts
- NiCu30Fe Fasteners
- BS 3076 NA13 Fasteners
- Nickel-Copper Alloy 400 Fasteners
These equivalent grades ensure global acceptance and interchangeability across international projects.
Key Features of Monel Alloy 400 Fasteners
- Excellent Corrosion Resistance: The unique characteristic of Monel 400 is its high resistance towards seawater, brackish water, alkali, and several acidic conditions.
- High Mechanical Strength: With remarkable strength within wide working temperature ranges, Monel Alloy 400 can also be used for several industrial applications demanding this feature.
- Excellent Marine Performance: Marine engineers frequently select Monel Alloy 400 Anchor Fasteners for shipbuilding, offshore structures, and seawater handling systems.
