Monel Boiler Tubing is mainly made up of 63% nickel and 30–34% copper, along with small amounts of iron, manganese, silicon, and carbon. This nickel-copper alloy boasts impressive corrosion resistance, especially in acidic and marine settings. Monel tubing offers a tensile strength ranging from 480 to 620 MPa and a yield strength between 170 and 345 MPa, depending on how it’s processed. It maintains excellent mechanical properties over a broad temperature range, provides good ductility, and withstands thermal stress and oxidation. Monel’s strength and ease of welding make it perfect for demanding high-pressure and high-temperature boiler and condenser applications.
