About Monel 400
Monel 400 nickel-copper alloy is a solid solution binary alloy combining high strength and toughness over a wide temperature range with excellent resistance to corrosion. Monel 400 alloy has been used at temperatures up to 800°F-1000°F in sulfur-free oxidizing atmospheres. It also displays excellent mechanical properties at sub-zero temperatures since it does not undergo a ductile-to-brittle transition even at such temperatures. This alloy is strengthened by cold work and is readily fabricated.
The composition of Monel 400 Alloy is given below:
|Nickel (plus Cobalt)||63.0 min.|
|Copper||28.0 – 34.0|
Applications of Monel Alloy 400
Monel Alloy 400 is a solid solution alloy that is hardened only by cold working. Due to its high strength and toughness over a wide temperature range, as well as excellent resistance to many corrosive environments, Monel Alloy 400 is typically used in marine engineering, chemical and hydrocarbon processing, heat exchangers, valves, and pumps.
Here is a summarized list of potential applications for Monel Alloy 400:
- Valves and pumps
- Pump and propeller shafts
- Marine fixtures and fasteners
- Chemical processing equipment
- Gasoline and fresh water tanks
- Crude petroleum tills
- Process vessels and piping
- Boiler feed water heaters, deaerating heaters, and other heat exchangers
Monel 400 Mechanical Properties
Monel 400 has excellent mechanical properties at subzero temperatures. Strength and hardness increase with only slight impairment of ductility or impact resistance. The alloy does not undergo a ductile-to-brittle transition even when cooled to the temperature of liquid hydrogen. This is in marked contrast to many ferrous materials which are brittle at low temperatures despite their increased strength.
Monel 400 exhibits resistance to corrosion by many reducing media. It is also generally more resistant to attack by oxidizing media than higher copper alloys. This versatility makes Monel 400 suitable for service in a variety of environments.
Monel 400 is widely used in marine applications. While Monel 400 products exhibit very low corrosion rates in flowing seawater, stagnant conditions have been shown to induce crevice and pitting corrosion. Monel 400 is also resistant to stress corrosion cracking and pitting in most fresh and industrial waters.
Monel 400 offers exceptional resistance to hydrofluoric acid in all concentrations up to the boiling point. It is perhaps the most resistant of all commonly used engineering alloys. Monel 400 is also resistant to many forms of sulfuric and hydrochloric acids under reducing conditions.
Characteristics of Monel 400
Is Monel 400 magnetic?
Monel 400 is slightly magnetic but only when kept at room temperature.
Monel 400 vs. Stainless Steel
One of the biggest differences between Monel 400 and Stainless Steel is that Monel 400 is made largely of nickel, while Stainless Steel is composed largely of iron. Due to this difference in composition, each has different benefits that might make it hard to decide on which to choose for a specific environment.
Monel 400 is much more corrosion resistant than stainless steel, especially in a saltwater environment or fuel tanks. Monel is also much stronger, but Stainless Steel is typically more magnetic than a Monel alloy.
Due to its nickel composition, Monel 400 is also duller in appearance than Stainless Steel. In terms of price, Monel is typically more expensive than Stainless Steel, but its benefits often make it a much better choice for specific environments.
Monel 400’s resistance to corrosion:
Monel 400 has a long history of superior corrosion resistance and is one of the few alloys that can be used in contact with fluorine, hydrofluoric acid, hydrogen fluoride, or their derivatives. In saltwater, Monel 400 also offers excellent corrosion resistance making it a great alloy for marine engineering. By reducing media, Monel 400 exhibits exceptional resistance even in hydrofluoric acid in all concentrations up to the boiling point.
Monel 400’s corrosion resistance is about the same as nickel, but with higher maximum working pressures and temperatures as well as at a lower cost due to its superior ability to be machined.
Is Monel ferrous or nonferrous?
Nickel alloys like Monel are non-ferrous metals, meaning they have exceptional strength and corrosion resistance. Non-ferrous metals are also excellent for high-temperature applications. Monel’s non-ferrous properties make it a suitable choice for marine applications such as deep-sea mining, where seawater poses the threat of corrosion.
