Nickel can alloy with other metals to create exceptionally strong, corrosion-resistant products with an average lifespan of 25 to 35 years. One popular nickel alloy is Monel® 400, or Nickel Alloy 400. This material is composed of about 67% nickel and 23% copper. Highly valued for its mechanical properties, like toughness and ductility, Monel® 400 is ideal for use in harsh environmental conditions.
Continental Steel and Tube Company offers Monel® 400 as stock items, with special production available for large quantities. We carry multiple forms for use in a wide variety of heavy-duty applications, including marine environments, chemical processing, heat exchangers, and more. Our metal specialists are committed to ensuring customer satisfaction and product excellence.

Monel® 400: Key Properties and Benefits
Monel® 400 is a popular material for components that must endure rigorous conditions. Some of its most notable properties include:
- Exceptional corrosion resistance. Monel® 400 performs well in both acidic and alkaline environments. It is resistant to most salts, seawater, steam, organic substances, and acids such as deaerated hydrochloric and hydrofluoric acid. It also resists corrosion under atmospheric conditions at both normal and elevated temperatures.
- High strength & toughness. As a high-strength alloy, Monel® 400 withstands exposure to high pressure and weight. It maintains its mechanical properties at subzero temperatures and is a reliable option for applications that require durability or impact resistance.
- Excellent ductility and thermal conductivity. Monel® 400 remains ductile even at low temperatures and is readily hot or cold-worked.
- Excellent weldability. Monel® 400 is easy to fabricate and join. It is compatible with multiple welding techniques, including gas metal arc, gas-tungsten arc, or shielded metal arc welding, with no required post-weld heat treatment.
- High melting point. Monel® 400 can withstand temperatures up to 1000 °C., making it a suitable option for demanding high-temperature environments.
Common Applications
Due to its impressive performance capabilities, Monel® 400 is used throughout a wide range of applications. Some of the most common uses for this alloy include:
- Chemical processing equipment. Since it can withstand exposure to corrosive chemicals, acids, and alkalis, Monel® 400 is common within the chemical processing industry. It is used to construct piping systems, tanks, vessels, and other processing equipment components.
- Heat exchangers. Monel® 400 offers high thermal conductivity and corrosion resistance, allowing it to efficiently transfer heat in numerous industrial processes.
- Marine applications. Due to its excellent corrosion resistance, Monel® 400 is used in many marine applications, including propeller shafts, pump shafts, and other components.
- Oil and gas industry. With its ability to withstand high pressures and extreme environments, Monel® 400 is a common material for constructing pipelines, valves, and fittings for the oil and gas industry.
