Duplex stainless steels have a mixed microstructure of austenite and ferrite, the aim usually being to produce a 50/50 mix, although in commercial alloys the ratio may be 40/60. Duplex stainless steels have roughly twice the strength compared to austenitic stainless steels and also improved resistance to localized corrosion, particularly pitting, crevice corrosion and stress corrosion cracking. They are characterized by high chromium (19–32%) and molybdenum (up to 5%) and lower nickel contents than austenitic stainless steels.


what is duplex stainless steel:

Duplex stainless steels have roughly twice the strength compared to austenitic stainless steels and also improved resistance to localized corrosion, particularly pitting, crevice corrosion and stress corrosion cracking.

duplex stainless steel properties:

Check it in our Tools & Specification section -> Duplex Steel

duplex stainless steel composition:

Duplex stainless steels are extremely corrosion resistant, work hardenable alloys. Their microstructures consist of a mixture of austenite and ferrite phases. As a result, duplex stainless steels display properties characteristic of both austenitic and ferritic stainless steels.


How tubing is different from Pipe?

  • Duplex Steel Pipe is available in many different types of materials and wall thicknesses, and sizes actually make sense.
  • Tubing is sized by the outside diameter or O.D. 1" tubing actually measures 1" on the outside diameter (within a few thousands of an inch.) Tubing wall thicknesses are measured in gauges up to a point then convert to fractions of an inch, some wall thicknesses are even measured in millimeters.
  • Outside diameters range from 1/8" and beyond 12". Wall thicknesses range between 20 gauge (.035") and 2" thick.
  • Tubing is available in many types of materials, some including: stainless steel, steel alloys (4130), aluminum (6061, 6063, 2011, 3003, with various heat treating), inconel, monel, hastelloy, and more.
  • Tubing is also available in many types of drawing and forming processes some including: (cold drawn seamless, buttweld, electrical resistance welded ERW, drawn over mandrel DOM, hot finished seamless) and others.
