Materialdesignation: Monel 400 (Monel) alloy
US grade: UNS N04400
German grade: 2.4360
I. Overview of Monel 400 (N04400)
Monel 400 (N04400) is a corrosion-resistantalloy with the largest amount, the most widely used, and excellentcomprehensive properties. This alloy has excellent corrosion resistance inhydrofluoric acid and fluorine gas medium, and also has excellent corrosionresistance to hot concentrated lye. Meanwhile, it is also resistant tocorrosion by neutral solutions, water, sea water, the atmosphere, organiccompounds and the like. An important feature of this alloy is that it generallydoes not produce stress corrosion cracking and has good cutting performance.Monel400 is more resistant to corrosion by reducing media than pure nickel, andmore resistant to corrosion by oxidizing media than pure copper.
