If you are looking out for a material which can withstand corrosive environments and withstand extreme critical conditions, then Monel 400 fasteners is the perfect product to be chosen.Composed of minimum 63% Nickel and Copper ranging between 29%-33%, they offer higher resistance not only in normal corrosive conditions but also to acids and alkalis.
They also have excellent tensile strength and good mechanical strength.They also can come in contact with Aluminium, Zinc and iron, making it an ideal use case for seawater and chemical industries.
We can not only heat Monel 400 bolts in normal conditions, such as at normal room temperatures, but also at extreme conditions, such as, hot and cold-working environments.They can be annealed and stress relieved to distort during subsequent machining.This also ensures added advantage of enhancing strength and ductility.
Annealing process: In annealing process, heating must be performed in sulphur-free reducing atmospheres.Ideal annealing temperature ranges between 1300–1800° F, but typical temperature range is 1600–1800° F.To avoid grain coarsening, low annealing temperatures ranging between 1300–1500° F.
Stress revealing: This process reduces stress without actually fractionally crystallizing the grain structure.Temperature for this process requires 1000/1050° F of heat for 1-2 hours, to relieve strains.
Alloy 400 bolts
UNS N04400 hex bolt
Monel alloy 400 nut
In environments such as sea water, acids and alkalis, alloy 400 hex bolt inherits good property of corrosion resistance and ensures that it does not rust or collide.
Due to the chemical composition of Nickel-Copper alloy mixture, they even have high tensile strength and good yield strength, which make them last for long period of time and even resist high temperature situations.
This bolt also prevents stress corrosion cracking in fresh and industrial waters.Adding to this factor, this ensures that it does not collide when exposed to extreme conditions.As a result, they are used mainly in marine, chemical and hydrocarbon processing applications.

When dealing with marine and offshore environments, there are many factors which can cause materials to corrode or rust.To deal with this we make use of UNS N04400 nut which make sure that it does not corrode as it inherits properties of corrosion resistance.
Adding to this, it is also resistant to chloride stress corrosion cracking and exhibit good stiffness or toughness over a wide range of temperatures.
Another advantage of using this material is that it can be fabricated by conventional processing techniques at a smooth rate.These are the main reason for its utilization in these industries as they require materials which last for long period and can withstand conditions which can be extreme and yield good results.
With respect to size, if the material is found to be less than 12 inches, then it is a Monel alloy 400 studs, and if the material is greater than or equal to 12 inches, then it is ASTM F467 Monel 400 threaded rod.
Nickel alloy 400 screws is Nickel based material which offers not only high corrosion resistance advantages, but also good machinability characteristics.It has machinability rating of 45% and 70 HRB hardness.Although Monel 400 is least hard when compares with Nickel-bases alloys, but with this percentage it still offers good machinability.
This is one of the reasons why it exhibits excellent strength and shows good corrosion resistance behaviour over wide range of temperatures.Adding to this, hardness also defines machinability characteristics.Another reason being the presence of Nickel in higher-levels (63%).This is one of the reasons why it is an ideal use case in chemical companies and marine engineering.
