Stainless Steel Pipe Duplex F55 UNS S32760 Corrosion Resistant Pipes

 

Duplex F55, often referred to by its UNS designation UNS S32760, is a super duplex stainless steel that is highly alloyed and designed for high strength and excellent corrosion resistance. It is not a nickel alloy but a stainless steel. It is composed primarily of iron, with a high percentage of chromium and nickel, and significant amounts of molybdenum and nitrogen, enhancing its corrosion resistance and strength. Here are detailed attributes and applications of Duplex F55 pipes:

Specifications and Standards

 

Duplex F55 pipes are produced according to international standards and specifications, such as:

 

  • ASTM A789 / ASME SA789 (Standard Specification for Seamless and Welded Ferritic/Austenitic Stainless Steel Tubing for General Service)
  • ASTM A790 / ASME SA790 (Standard Specification for Seamless and Welded Ferritic/Austenitic Stainless Steel Pipe)

 

Applications

 

  • Oil and Gas Industry: Equipment such as pipes, valves, pumps, and heat exchangers that require excellent corrosion resistance and high strength in sour environments often use super duplex materials.
  • Desalination Plants: The sea-water resistance of F55 makes it suitable for high-pressure piping and other components in desalination plants.
  • Chemical Processing: Because of its resistance to a wide variety of chemicals, super duplex stainless steel is used in reactors, tanks, and piping in chemical processing industries.
  • Marine and Shipping Industry: Its strength and corrosion resistance in marine environments make it suitable for use in shafts, rudders, and shaft seals.

 

Physical and Mechanical Properties

 

  • Density: Approximately 7.8 g/cm³
  • Tensile Strength: Around 750 MPa to 930 MPa
  • Yield Strength (0.2% Offset): Minimum 550 MPa
  • Elongation: About 25% minimum

 

Duplex F55 is distinguished by its superior combination of mechanical strength and corrosion resistance, making it a material of choice for critical applications that require both high-performance and long-lasting durability in aggressive environments. It is widely used for piping systems and other components in demanding sectors like offshore oil and gas, chemical processing, and marine engineering.
