What Are Duplex 2205 Round Bars?
Duplex 2205 round bars are high-strength stainless steel bars composed of a balanced mix of austenite and ferrite phases. This unique composition provides enhanced mechanical strength and superior corrosion resistance compared to standard stainless steels.
These bars are widely used in applications where resistance to stress corrosion cracking and pitting is essential.
Chemical Composition of Duplex 2205 Bar
The composition of Duplex 2205 round bars typically includes:
- Chromium: 21–23%
- Nickel: 4.5–6.5%
- Molybdenum: 2.5–3.5%
- Nitrogen: 0.08–0.20%
This combination enhances both corrosion resistance and mechanical strength, making the material ideal for harsh environments.
Key Specifications of Duplex 2205 Round Bars
Duplex 2205 round bars are manufactured according to international standards to ensure quality and reliability:
- Standards: ASTM A276, ASTM A479
- Grade: UNS S32205 / S31803

Key Properties of Duplex stainless steel 2205 bars
1. High Strength
One of the most notable features of Duplex 2205 Round Bars is their superior strength, which is nearly double that of standard austenitic stainless steels like 304 and 316.
2. Excellent Corrosion Resistance
These bars offer outstanding resistance to pitting, crevice corrosion, and chloride stress corrosion cracking, making them ideal for harsh environments.
3. Good Weldability
Despite their high strength, Duplex 2205 round bars can be welded using standard methods, ensuring ease of fabrication.
4. Resistance to Stress Corrosion Cracking
They perform exceptionally well in chloride-rich environments, where other materials may fail.
5. Cost Efficiency
Due to their high strength, less material is required for the same application, making Duplex 2205 Round Bars a cost-effective solution.
