Monel Tubing is dominated by about 67% nickel and 30% copper with trace amounts of iron, manganese, and other trace elements. This alloy provides superior resistance to corrosion by seawater, acidic and alkaline environments, and oxidizing and reducing agents. Mechanically, Monel Tubing is characterized by high tensile strength, superior ductility, and toughness over a broad range of temperatures. Some of the common grades are Monel 400 and Monel K500—Monel 400 provides general corrosion resistance and Monel K500 offers higher strength through precipitation hardening. The tubing can be both seamless or welded, depending on the need of the application in terms of pressure and temperature.
