Monel400 is an amount of the largest and most versatile, excellent overall performance of corrosion resistant alloys. This alloy has excellent corrosion resistance in hydrofluoric acid and fluorine gas medium, hot concentrated alkali also has excellent corrosion resistance. Also resistant to neutral solution, water, sea water, air, organic compounds such as corrosion. An important feature of the alloy is generally not produce stress corrosion cracking, good cutting performance.
The chemical composition of an alloy mainly composed Monel400 30% Cu and 65% Ni plus a small amount of Fe (1% -2%) of the composition. Organizational structure for the typical single-phase austenite. Since nickel and copper can be soluble in any ratio, it is generally no intermetallic phase precipitation. In the non-etching conditions microscope Watch this alloy, showing a very diffuse miscellaneous non-metallic inclusions on the austenite matrix, such as sulfides and silicates. Under certain conditions, it can be observed that there exists a carbide.
