1. What is a Monel 400(N04400) sheet/plate?
Monel 400 (N04400) is a soft copper-nickel alloy that is resistant to various corrosive environments. The alloy is often named for use in mild oxidizing environments, neutral environments, and progressively weakening environments. Another area of application is in marine environments and other non-oxidizing chloride solutions.
Monel 400 (N04400) This alloy has a long history as a corrosion-resistant material, dating back to the 20th century. At the time, it was intended to be used as a nickel metal with a high copper content. The nickel-copper content in the metal is roughly even and is now officially specified as a requirement for the production of the alloy. As a commercially available pure nickel, Monel400 copper-nickel alloy has low strength under annealed conditions. For this reason, various tempering methods must be used to increase the strength of the material.
2. Chemical composition of Monel 400(N04400) sheet/plate
Monel400 alloy's primary chemical components are 30% Cu and 65% Ni, with a trace quantity of Fe (1%–2%) being present. A typical single-phase austenite structure describes the organizational structure. There is typically no intermetallic phase precipitation since nickel and copper are soluble in any ratio.
It is possible to discern that the austenite matrix of this alloy contains very dispersed non-metallic inclusions, such as sulfides and silicates, under non-etching conditions using a metallographic microscope. Additionally, the existence of carbides may be seen under specific circumstances. It can come in a range of alloy grades due to variations in chemical makeup, although there aren't any really noticeable distinctions in how well they resist corrosion. In comparison to pure nickel and pure copper, the monel400 alloy is more resistant to corrosion when exposed to reducing and oxidizing environments, respectively.
