SB163 Monel 400 Nickel-Copper Alloy Tube UNS N04400 Distillation Columns

Overview

Monel 400 is a high-performance nickel-copper alloy known for its excellent resistance to corrosion, particularly in seawater and other harsh environments. It is widely used in industries where high strength, resistance to corrosion, and good weldability are essential. Monel 400 alloy contains around 63% nickel and 28-34% copper, along with small amounts of iron, manganese, carbon, and silicon. Below is a more detailed overview of the material.

Intended for use in applications involving condenser and heat exchanger processes, Sb-163 tubing materials cover a wide range of sizes. For example, Sb 163 N04400 alloy 400 tubing built to specification covers not only the outside diameter, but also its average wall thickness. In addition, Monel 400 seamless tubing includes dimensions such as outside diameter and minimum wall tubing. Monel Alloy 400 tubing is slightly magnetic at ambient temperatures and at high temperature settings, Monel Alloy 400 tubing can resist seawater and steam as it resists salt and caustic alkali solutions.
