UNS32550 1.4507 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:

  1. 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.
  2. 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.
  3. 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.
  4. 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.
  5. 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.

UNS32550 1.4507 Material Summary

Super duplex UNS S32550 is a stainless steel grade that offers excellent corrosion resistance in a wide variety of corrosive chemicals including sulphuric, phosphoric and nitric acids. In Seawater and other chloride containing environments 32550 also provides outstanding resistance to pitting and crevice corrosion, with Critical Pitting Temperature exceeding 50°C.


RESISTANCE TO CORROSION

Excellent ductility and impact strength at both ambient and sub-zero temperatures combine with a high resistance to abrasion, erosion and cavitation erosion.

UNS S32550 Displays superior corrosion resistance in most media. Also, 2550 typically out performs duplex alloy 2205. It performs well in sulphuric, phosphoric, and nitric and shows excellent resistance to organic acids such as acetic and formic acid. Highly reducing media should be avoided.
