Duplex 2205 is commonly associated with:
UNS S31803
and
UNS S32205
UNS S32205 is commonly used for the higher-nitrogen version of the 2205 grade with tighter composition requirements.
Because both designations appear in industrial purchasing, the exact UNS grade specified by the customer should be confirmed before quotation.
ASTM A276 Duplex 2205
ASTM A276 covers stainless steel bars and shapes within its scope.
Duplex stainless-steel bars can be supplied to applicable requirements of this standard.
A purchase enquiry should mention:
- Grade
- UNS number
- ASTM specification
- Diameter
- Length
- Condition
- Quantity
- Testing
- Certification
Current requirements should be checked against the applicable ASTM edition through ASTM International.
ASTM A479 Duplex 2205
ASTM A479 covers stainless steel bars and shapes for use in pressure vessels and other applications within its scope.
Duplex 2205 can be specified under applicable requirements of this standard.
For pressure-related projects, always confirm whether the customer requires:
ASTM A276
or
ASTM A479
along with the exact UNS designation.
Duplex 2205 Chemical Composition
Duplex 2205 is primarily an iron-based stainless steel alloy containing important amounts of:
- Chromium
- Nickel
- Molybdenum
- Nitrogen
It also contains controlled amounts of:
- Carbon
- Manganese
- Silicon
- Phosphorus
- Sulfur
Chromium, molybdenum and nitrogen contribute significantly to the alloy’s corrosion resistance.
The actual chemical composition should always be verified against the applicable specification and Material Test Certificate.
Duplex 2205 Properties
Important Duplex 2205 properties include:
- High yield strength

It also offers good resistance to stress corrosion cracking in many chloride-containing environments.
Actual performance depends on concentration, temperature, oxygen content and other service conditions.
Duplex 2205 Pitting Resistance
Pitting corrosion is a localized form of corrosion that can be particularly damaging in chloride environments.
Duplex 2205’s chromium, molybdenum and nitrogen content contributes to its resistance to pitting and crevice corrosion.
This makes it relevant to:
- Marine equipment
- Chemical processing
- Desalination
- Oil and gas
- Offshore equipment
Duplex 2205 PREN
PREN, or Pitting Resistance Equivalent Number, is commonly used as an indicator when comparing the potential pitting resistance of stainless-steel grades.
Duplex 2205 has a relatively high PREN because of its chromium, molybdenum and nitrogen content.
However, PREN should not be treated as a complete prediction of actual corrosion performance.
Real service conditions must always be considered.
