Applications

• UNS S32550, also known as FERRALIUM 255, is a duplex stainless steel alloy with remarkable properties. Let's explore its applications in various industries:
• Chemical Processing:
  • FERRALIUM 255 is widely used in chemical processing equipment due to its excellent resistance to highly acidic environments.
  • It finds applications in reactors, heat exchangers, and other components exposed to aggressive chemical media.
• Marine Engineering:
  • In marine environments, FERRALIUM 255 is suitable for marine fixtures, pump and mixer shafts, and other components.
  • Its ability to withstand saltwater corrosion ensures longevity in harsh conditions.
• Seawater Desalination Plants:
  • The alloy is commonly used in desalination plants due to its high resistance to pitting and crevice corrosion.
  • It ensures efficient operation in these critical facilities.
• Oil and Gas Industry:
  • FERRALIUM 255 is a cost-effective alternative to materials such as nickel alloys and brass.
  • It finds applications in offshore platforms, deck hardware, rudders, shafting, and other components.
• Paper Industry:
  • FERRALIUM 255 has been used to replace conventional stainless steel equipment in the paper industry.
  • It addresses corrosion problems caused by environmental laws that forced recycling of process liquids.
• Remember that FERRALIUM 255 combines the desirable aspects of both austenitic and ferritic grades, making it valuable in demanding industrial settings.

Packaging & Shipping

1.generally export packing

   -packed by knitting strips in bundles

2.It is suggested that the pipes OD under 25MM or Less than container shipment are packed by plywood cases, which can protect pipes better.
