Monel 400 plate information details
Monel 400 plate is a nickel-copper alloy known for its high strength, excellent corrosion resistance and good weldability. It is particularly resistant to a variety of acids and bases, including hydrofluoric and hydrochloric acids, and is widely used in marine environments. The alloy can be hardened by cold working and is suitable for temperatures ranging from sub-zero to 1000°F (538°C).
What is the composition of Monel 400 Plate?
Monel 400 alloy plate is a nickel-copper alloy (approximately 67% nickel - 23% copper) that is resistant to high temperatures of seawater and steam, as well as saline and alkaline solutions. 400 alloy plate is a solid solution alloy that can only be hardened by cold working.
