2205 Duplex/Super Duplex Stainless Steel (1.4462,UNS S31803/UNS S32205)

The yield strength is about twice that of austenitic stainless steels, thus allowing a designer to save weight and making the alloy more cost competitive when compared to 316L or 317L.

 

Alloy 2205 (UNS S32305/S31803) is a 22% chromium, 3% molybdenum, 5-6% nickel, nitrogen alloyed duplex stainless steel with high general, localized, and stress corrosion resistance properties in addition to high strength and excellent impact toughness.
Alloy 2205 provides pitting and crevice corrosion resistance superior to 316L or 317L austenitic stainless steels in almost all corrosive media. It also has high corrosion and erosion fatigue properties as well as lower thermal expansion and higher thermal conductivity than austenitic.

 

Duplex 2205, also known as UNS S32205, is a nitrogen-enhanced stainless steel. Users choose Duplex 2205 for its excellent corrosion resistance along with its high strength. It is important to note that Duplex 2205, offers much higher levels of corrosion resistance than most other austenitic stainless steels. Other benefits include:

 

  • High resistance to pitting and crevice corrosion
  • Excellent in most caustic environments
  • Good weldability

 

To be considered Duplex 2205, a stainless steel must have a chemical composition that includes:

  • Cr 21-23%
  • Ni 4.5-6.5%
  • Mn 2% Max
  • Mo 2.5-3.5%
  • N 0.08-0.20%
  • P 0.30% max
  • C 0.030% max

 

Specifications of Duplex Stainless Steel Welded Tube

 

1. Standard: ASTM ASME
2. Grade: 630 / 631 / 2205 / 2507 / 17-4PH
ASTM A789, ASTM A790, ASTM A450, ASTM A530,
GB/T 14976, GB/T 14975, GB/T 13296, etc
3. OD: 8mm-1000mm
4. Wall thickness: 0.3mm-30mm
5. Length: max.18000mm or as demand

6. Surface finish: Polishing (180#,220#,240#,320#400#,600#), Hairline, acid pickled, etc.

The advantage of a duplex structure is that it combines the favorable qualities of a ferritic alloy (stress corrosion cracking resistance and high strength) with those of an austenitic alloy (ease of fabrication and corrosion resistance).

Usage of 2205 Duplex stainless steel should be limited to temperatures below 600° F. Extended elevated temperature exposure can embrittle 2205 stainless.
