Alloy 400, also known as Monel 400, is a high-performance nickel-copper alloy renowned for its exceptional resistance to a variety of corrosive environments. With a composition of approximately 63% nickel and 28-34% copper, along with trace amounts of iron, manganese, and silicon, this alloy was one of the earliest nickel-copper materials developed and remains widely used today due to its unique balance of strength, corrosion resistance, and durability.
Nickel alloy 400 pipe is particularly valued for its ability to withstand harsh conditions, including exposure to seawater, sulfuric and hydrochloric acids, alkaline solutions, and various industrial chemicals. This makes it an ideal choice for critical applications in the marine industry, chemical processing plants, and oil and gas operations. Similarly, alloy 400 tube is commonly used in high-performance heat exchangers, steam generators, and condenser systems, ensuring long-term reliability in extreme environments.
