Super Duplex S32760 Pipes are widely utilized in various industries such as oil and gas, petrochemical, chemical, and more. This type of pipe is designed to perform well under extreme temperatures, pressures, and corrosive environments. If you are interested in using Super Duplex S32760 Pipes, it’s essential to learn more about its composition, physical and mechanical properties, uses, heat treatment, and corrosion resistance. In this blog post, we will provide all the information you need to know about Super Duplex S32760 Pipes.
What is Super Duplex S32760 Pipes?
Super Duplex 32760 Pipe is a stainless steel alloy of 25% chromium, 7% nickel, 3.2% molybdenum, and 0.2-0.3% nitrogen with a minimum PREN (Pitting Resistance Equivalent Number) of 41. This combination gives it superior strength to other austenitic steels and offers excellent resistance to corrosion in environments with high chlorides, such as seawater and sulphuric acid applications.
Super Duplex S32760 Pipes Composition:
UNS S32760 Pipes comprise a high percentage of Chromium, Molybdenum, and Nitrogen. These elements enhance the pipe’s strength, corrosion, and pitting resistance. In addition, the pipe contains a mix of austenite and ferrite microstructures, which increases its toughness, durability, and weldability.

Super Duplex S32760 Pipes Uses:
UNS S32760 Seamless Pipe are used widely in petrochemical, oil and gas, chemical, and other industries. They are preferred in environments with a high chloride concentration, making them an excellent choice for offshore oil and gas platforms in the North Sea, West Africa, and the Gulf of Mexico. These pipes can withstand high pressure and extreme temperatures, making them perfect for petrochemical and chemical plants.
Super Duplex S32760 Pipes heat treatment:
The heat treatment of Super Duplex S32760 Pipes is critical to ensure its toughness and strength. The process involves heating the pipe to a specific temperature, holding it there for a specified period, and then cooling it down. This heat treatment process enhances the pipe’s mechanical properties while improving its corrosion resistance.
Super Duplex S32760 Pipes corrosion resistance:
One of the most significant benefits of UNS S32760 Seamless Pipe is its exceptional corrosion resistance. The addition of Molybdenum, Nitrogen, and Chromium in the composition of the pipe increases its corrosion resistance, making it ideal for harsh environments. Super Duplex S32760 Pipes are not only resistant to chloride-induced stress corrosion cracking but also resistant to crevice corrosion, pitting and erosion.
In conclusion, Super Duplex 32760 Pipe is an excellent choice for industries that require a type of pipe that can withstand high pressure, extreme temperature, and corrosive environments. Its composition, physical and mechanical properties, uses, heat treatment and corrosion resistance are exceptional. By understanding everything there is to know about Super Duplex S32760 Pipes, you can ensure that you make an informed decision when looking for a pipe to fit your specific needs.
