Monel400 USA UNS: N04400, Germany DIN: NICU30FE W-NR: 24360 China GB T: MCU-28-15-1.8 UK BS: NA 12 Chemical Composition Designator: NI68CU28FE, round bar, strip, plate, wire, thin strip, forged ring, MOEL400 (UNS N04400) copper-nickel alloy introduction.
Monel400 is an alloy composed of copper and nickel, and its chemical composition is mainly composed of 30% copper and 65% nickel with a small amount of iron. Due to its peculiar chemical composition, Monel400 is available in a variety of alloy grades, but there is no significant difference in corrosion resistance between them. Compared to pure nickel, Monel400 alloy is more resistant to corrosion by reducing media, while it is more resistant to corrosion by oxidizing media compared to pure copper.
Monel400 alloy has a wide range of applications worldwide and has been recognized by several national and international standards. In the United States, it is standardized as UNS N04400, while in China, it has a standard number of GBT MCU-28-15-1.8。This alloy is used in a wide variety of applications, especially where excellent corrosion resistance is required.
The chemical composition of Monel400 alloy is very stable, and the ratio of elements in it is carefully formulated to ensure its corrosion resistance in a variety of environments. For example, nickel provides corrosion resistance to reducing media, while copper enhances the alloy's resistance to oxidizing media. In addition, a small amount of iron is also added to the alloy to further enhance its overall properties.
In addition to its excellent corrosion resistance, Monel400 alloy has many other excellent properties. It has a tensile strength of B 450MPa, a yield strength of B 170MPa, and an elongation of δ 30%, which make it a very strong and reliable metal material. Another important property of Monel400 alloy is that it does not produce stress corrosion cracks, which makes it an ideal choice for many applications.
Although Monel 400 alloy exhibits excellent corrosion resistance in many environments, each alloy has its own specific conditions and limitations of use. Therefore, when using Monel400 alloy, its performance characteristics and use environment should be fully understood to ensure its long-term stability and reliability.
Overall, Monel400 alloy is a copper-nickel alloy with excellent corrosion resistance and mechanical properties, and it has a wide range of applications in many fields. With the continuous development of science and technology, we believe that MONAL400 alloy will be applied and promoted in more fields.
