2205 duplex stainless steel pipe is a nitrogen-enhanced duplex grade with a two-phase microstructure consisting of approximately 50% austenite and 50% ferrite. This balanced structure provides approximately twice the yield strength of standard austenitic stainless steels such as 304 and 316, combined with excellent corrosion resistance.
2205 is the most widely used duplex stainless steel grade, offering an exceptional combination of high strength, good weldability, and superior resistance to stress corrosion cracking, pitting, and crevice corrosion.

UNS S32205 has tighter compositional limits than UNS S31803, providing improved corrosion resistance and consistency.
| Property | Value |
|---|---|
| Tensile Strength | ≥ 620 MPa (≥ 90 ksi) |
| Yield Strength (0.2% offset) | ≥ 450 MPa (≥ 65 ksi) |
| Elongation | ≥ 25% |
| Hardness (Brinell) | ≤ 290 HB |
| Hardness (Rockwell C) | ≤ 30 HRC |
| Impact Strength (Charpy V-notch) | ≥ 100 J at -40°C |
Note: The values above are for reference only. Please refer to the mill test certificate for actual data.
| Property | Value |
|---|---|
| Density | 7.8 g/cm³ |
| Modulus of Elasticity | 200 GPa (29,000 ksi) |
| Thermal Conductivity (100°C) | 19 W/m·K |
| Specific Heat (0-100°C) | 500 J/kg·K |
| Electrical Resistivity | 850 μΩ·m |
| Magnetic Permeability | Magnetic (ferritic phase) |
| Process | Recommendation |
|---|---|
| Welding | Use matching filler metal (2209). Control heat input (0.5-2.5 kJ/mm). Avoid overheating. |
| Bending | Minimum bend radius of 3x OD for cold bending. Use mandrel for tight radii. |
| Cutting | Use abrasive saw or cold saw. Avoid thermal cutting to prevent intergranular corrosion. |
| Machining | Use rigid tooling and positive rake angles. Lower speeds and higher feeds than austenitic. |
| Heat Treatment | Solution anneal at 1040-1100°C followed by water quenching. |
