2205 Stainless Steel Pipe is a widely used duplex grade combining high mechanical strength with excellent resistance to pitting, crevice corrosion, and chloride stress corrosion cracking. Its balanced austenitic-ferritic microstructure provides a strong performance-to-weight ratio. 2205 pipe is commonly selected for oil and gas, chemical processing, marine, desalination, pressure equipment, and industrial piping exposed to chloride-containing environments.

| C | ≤0.030 |
| Si | ≤1.00 |
| Mn | ≤2.00 |
| P | ≤0.030 |
| S | ≤0.020 |
| Cr | 22.0–23.0 |
| Ni | 4.5–6.5 |
| Mo | 3.0–3.5 |
| N | 0.14–0.20 |
| Other | Fe: Balance |
Mechanical Properties
| Condition | Tensile Strength | Yield Strength (0.2%) | Elongation | Hardness |
