The length of the Nickel Alloy 400 Plate ranges from 200mm to 6000mm and the width ranges from 1000mm to 2000mm and the thickness varies from 0.3mm to 20mm. The Monel 400 Coil is also hard with NACE MR 175 hardness score. The UNS N04400 Strip can come in different finishes such as the hot rolled or cold rolled finishes. The Alloy UNS N04400 Shim Sheet supports, cutting, forming, grinding and polishing operations. The chemical composition of UNS N04400 Strip includes 63% nickel, iron, 28% copper, carbon, manganese, silicon and sulfur.

The UNS N04400 Strip is a narrow form of the plate. Monel 400 Plate is used in lining applications and to fill in gaps in larger plate structures. The Monel 400 Coils are also used to produce pipes and tubes of the same grade of material. The material has higher density than the 304 grade steels. The density is 8.8 grams per centimeter cube. As one of the leading Monel 400 Coil Suppliers, HT PIPE manufactures and supplies the Alloy 400 Plates for various high temperature applications. The high operating temperature of the material comes from the high melting point of 1350 degrees Celsius. Nickel Alloy 400 Sheet also has 240MPa minimum yield strength and 550MPa minimum tensile strength.

Chemical Composition, %

Corrosion Resistant Monel 400

Alloy 400 is virtually immune to chloride ion stress corrosion cracking in typical environments. Generally, its corrosion resistance is very good in reducing environments, but poor in oxidizing conditions. It is not useful in oxidizing acids, such as nitric acid and nitrous. Nevertheless, it is resistant to most alkalis, salts, waters, food products, organic substances and atmospheric conditions at normal and elevated temperatures.

This nickel alloy is attacked in sulfur-bearing gases above approximately 700° F and molten sulfur attacks the alloy at temperatures over approximately 500° F. Monel 400 offers about the same corrosion resistance as nickel but with higher maximum working pressures and temperatures and at a lower cost due to its superior ability to be machined.

In what applications is Monel 400 used?
• Marine engineering
• Chemical and hydrocarbon processing equipment
• Gasoline and freshwater tanks
• Crude petroleum stills
• De-aerating heaters
• Boiler feed water heaters and other heat exchangers
• Valves, pumps, shafts, fittings, and fasteners
• Industrial heat exchangers
• Chlorinated solvents
• Crude oil distillation towers

Fabrication with Monel 400
Alloy 400 can easily be welded by gas-tungsten arc, gas metal arc or shielded metal arc processes using appropriate filler metals. There is no need for post weld heat treatment, however, thorough cleaning after welding is critical for optimum corrosion resistance, otherwise there is the risk of contamination and embrittlement.

Finished fabrications can be produced to a wide range of mechanical properties when proper control of the amount of hot or cold working and the selection of appropriate thermal treatments is done.

Like most other nickel alloys, Monel 400 is typically tough to machine and will work harden. However, excellent results can e obtained if you make the correct choices for tooling and machining.
