Alloy 2205 is a widely used duplex stainless steel pipe/tube, characterized by a balanced microstructure of approximately 50% austenite and 50% ferrite. This unique composition grants it a superior blend of strength, corrosion resistance, and versatility, making it a preferred choice in various industrial applications. Available under designations such as UNS S31803, UNS S22053, and EN 1.4462, these pipes are commonly produced in a 5.8m length, offering practicality for installation and fabrication. Alloy 2205 pipes excel in both moderate and aggressive environments, bridging the performance gap between austenitic and ferritic stainless steels.
Chemical Composition (Weight %)
| Element | Content Range |
|---|---|
| Chromium (Cr) | 21.0 - 23.0 |
| Nickel (Ni) | 4.5 - 6.5 |
| Molybdenum (Mo) | 2.5 - 3.5 |
| Nitrogen (N) | 0.08 - 0.20 |
| Iron (Fe) | Balance |
| Carbon (C) | ≤ 0.03 |
| Manganese (Mn) | ≤ 2.0 |
| Silicon (Si) | ≤ 1.0 |
| Phosphorus (P) | ≤ 0.035 |
| Sulfur (S) | ≤ 0.02 |
Mechanical Properties
| Property | Value |
|---|---|
| Tensile Strength | ≥ 620 MPa |
| Yield Strength (0.2% offset) | ≥ 450 MPa |
| Elongation | ≥ 25% |
| Hardness (Rockwell C) | ≤ 29 |
| Impact Strength (Charpy V-notch, -40°C) | ≥ 60 J |
Key Features
- Superior Corrosion Resistance: Resistant to pitting, crevice corrosion, and stress corrosion cracking in chloride-containing environments, such as seawater and industrial effluents.
- High Strength: Offers approximately twice the yield strength of austenitic stainless steels (e.g., 304, 316), enabling thinner wall designs and reducing overall system weight.
- Excellent Weldability: Can be welded using standard techniques (TIG, MIG) with minimal risk of embrittlement when proper procedures are followed.
- Good Toughness: Maintains ductility and impact resistance across a wide temperature range, including low temperatures.
- Cost-Effective: Provides better performance than standard austenitic steels at a competitive price point, making it suitable for large-scale applications.
Standards
Alloy 2205 pipes/tubes are manufactured in accordance with international standards to ensure quality and consistency:
- ASTM A789 / A789M (Seamless and Welded Ferritic/Austenitic Duplex Stainless Steel Tubing)
- ASTM A790 / A790M (Seamless and Welded Ferritic/Austenitic Duplex Stainless Steel Pipe)
- ASME SA789 / SA790
- EN 10216-5 (Welded duplex stainless steel tubes for pressure purposes)
- DIN 17458 (Duplex stainless steel pipes)
- JIS G3463 (Stainless steel pipes for general piping)
Equivalent Grades
- UNS S31803 (original grade)
- UNS S22053 (updated grade with tighter nitrogen control)
- EN 1.4462
- DIN X2CrNiMoN22-5-3
- JIS SUS 2205
Applications
Alloy 2205 pipes, especially in the 5.8m length, are widely used in industries requiring a balance of strength and corrosion resistance:
- Oil and gas: Offshore pipelines, wellhead equipment, and subsea systems.
- Chemical processing: Reactors, heat exchangers, and piping for handling acids and chlorides.
- Water treatment: Desalination plants, wastewater treatment systems, and reverse osmosis equipment.
- Pulp and paper: Bleaching lines and chemical storage tanks.
- Marine engineering: Shipbuilding, ballast systems, and coastal infrastructure.
- Construction: Structural components in corrosive environments, such as bridges and coastal buildings.
Export Packaging & Transportation
-
Packaging:
- 5.8m length pipes are bundled with heavy-duty steel straps to prevent shifting.
- Each bundle is wrapped in waterproof plastic or Hessian cloth to protect against moisture, dust, and scratches.
- Smaller quantities or custom lengths may be packed in wooden crates with foam padding for added protection.
- Every package includes labels with details: material grade, size, length, quantity, heat number, and certification (e.g., Mill Test Report).
-
Transportation:
- Shipped via container ships (20ft or 40ft containers) for international exports, with proper bracing to secure bundles.
- Land transport uses flatbed trucks or railcars, with straps and blocking to ensure stability during transit.
- Special handling is provided for oversized or heavy pipes to maintain structural integrity.
