Monel 400 round bars are a premium nickel-copper alloy product known for exceptional strength, corrosion resistance, and durability across a wide range of industrial applications. Engineered from an alloy containing approximately 67% nickel and 23% copper, Monel 400 offers unique performance advantages, especially in marine, chemical, and high-temperature environments.
What Is Monel 400?
Monel 400 is a solid solution alloy that maintains its mechanical properties over a wide temperature range and exhibits excellent resistance to corrosive media. It is particularly effective against seawater, hydrofluoric acid, and alkalis, making it a preferred choice for applications that demand long service life and resistance to harsh chemical exposure.
Unlike many stainless steels, Monel 400 resists stress corrosion cracking and retains its non-magnetic nature even after cold working. It also offers good weldability and moderate-to-high strength.
Key Properties of Monel 400 Round Bars
