Monel 400 Pipe
Monel 400 Pipe
Monel 400 pipe is a robust nickel-copper alloy (around 67% Ni, 30% Cu) known for exceptional corrosion resistance, especially in marine environments, acids, and alkalis, offering excellent strength from sub-zero to high temperatures (up to 1000°F) and toughness. It’s used in demanding applications like chemical processing, oil & gas, heat exchangers, and seawater systems, available in various forms (seamless, welded, round, square) and conditions (annealed, pickled) to meet stringent industry standards (ASTM B165, UNS N04400).

Key Properties of
Monel 400 Pipe
Monel 400 pipe primarily consists of nickel (minimum 63%) and copper (maximum 34%), with trace amounts of iron, manganese, carbon, and silicon.
It exhibits excellent corrosion resistance against seawater, reducing acids, and alkalis.
Combining high strength and toughness, it maintains performance under extreme temperatures.
It can only be hardened through cold working and cannot be hardened by heat treatment.
