Monel is a nickel-copper alloy that falls into the category of High Nickel Alloys and contains iron, manganese, sulfur, and silicon fragments. The cold working process can help to strengthen it. It has excellent corrosion resistance and high strength and toughness over a wide temperature range. Monel 400 tube material has a minimum yield strength of 240MPa and a minimum tensile strength of 550MPa.
Features of Monel 400 Tubes
- Monel 400 is a solid nickel alloy solution that contains 52-67 percent nickel and 28-34 percent copper and can only be hardened by cold working.
- Monel 400 Tube is stronger than nickel, extremely corrosion resistant, and highly weldable.
- It has excellent corrosion resistance as well as good strength and durability over a wide temperature range.
- Monel 400 tubes can withstand high-temperature sea water, steam, salt, and caustic solutions.
- It has a high resistance to deaerated hydrochloric and hydrofluoric acids.
- At room temperature, the alloy is slightly magnetic.
- Monel’s mechanical properties range from subzero to 480 degrees Celsius.
- This alloy is more resistant to nickel in reducing conditions and to copper in oxidizing conditions; however, it is more resistant to reducing media than to oxidizing media.
- It is resistant to seawater and corrosion in a wide range of marine and chemical environments. Acids range from pure water to non-oxidizing mineral salts and alkalis.
Uses and Applications of Monel 400 Tubes
- Alloy 400, also known as Monel 400 tube, is widely used in a variety of industries, particularly the marine and chemical industries.
- Sulfuric and hydrofluoric acid alkylation plants also use it.
- Typical applications include valve and pump shafts, naval fixtures and fasteners, electrical and mechanical components, springs, and chemical processing machinery.
- Monel 400 tubes can also be found in fuel and fresh water containers, crude petroleum refining vessels and piping, boiler feed water heaters and other heat exchangers, and de-aerating heaters.
- It has numerous applications, including fuel tanks and electronic components. Monel 400 Tube is commonly used in chemical processing equipment, hydrocarbon processing equipment, marine engineering, pipes, fittings, fasteners, pumps, shafts, and heat exchangers.
- Monel 400 Seamless Pipes are resistant to corrosion in both acidic and alkaline environments.
