| High Light | Duplex Stainless Steel Pipe UNS S32101 ，Structural Duplex Stainless Steel Pipe | ||
UNS S32101 is a lean duplex stainless steel grade that offers a balanced combination of good strength, excellent corrosion resistance, and cost-effectiveness. It belongs to the lean duplex family (also known as LDX 2101®), containing lower nickel and molybdenum than standard duplex grades like 2205, making it a more economical alternative without significantly compromising performance.
Manufactured in accordance with ASTM A789 and ASTM A790, UNS S32101 tubes are available in both seamless and welded forms, suitable for a wide range of industrial applications.
Key distinction: As a lean duplex grade, S32101 offers approximately twice the yield strength of 304/316L while containing less nickel, providing better price stability and lower material cost.
| Parameter | Range |
|---|---|
| Outer Diameter (OD) | 6.0 mm – 219 mm (1/8″ – 8″) |
| Wall Thickness (WT) | 0.5 mm – 15 mm |
| Length | Customized (up to 12 meters or as required) |
| Type | Seamless / Welded (cold finished) |
| End Finish | Plain end, beveled end, threaded, or grooved |
Note: For larger diameters (> 8″), refer to ASTM A790 UNS S32101 pipe.
| Feature | Description |
|---|---|
| High Strength | Minimum yield strength ≥ 450 MPa (65 ksi) – approximately 2x stronger than 304/316L |
| Good Corrosion Resistance | Resistant to pitting, crevice corrosion, and stress corrosion cracking (SCC) |
| Low Nickel Content | Only 1.35 – 1.70% Ni – reduces material cost and price volatility |
| Chloride Resistance | Suitable for brackish water, mild seawater, and chloride-containing environments |
| Excellent Weldability | Easy to weld with standard methods; no preheating required |
| Cost-Effective | Lower cost than 2205, S31803, and super duplex grades |
| High Mechanical Properties | Good impact toughness even at low temperatures |
| Element | UNS S32101 Requirements |
|---|---|
| Carbon (C) | ≤ 0.040 |
| Silicon (Si) | ≤ 1.00 |
| Manganese (Mn) | 4.0 – 6.0 |
| Chromium (Cr) | 21.0 – 22.0 |
| Nickel (Ni) | 1.35 – 1.70 |
| Molybdenum (Mo) | 0.10 – 0.80 |
| Nitrogen (N) | 0.20 – 0.25 |
| Copper (Cu) | 0.10 – 0.80 |
| Phosphorus (P) | ≤ 0.040 |
| Sulfur (S) | ≤ 0.020 |
| Iron (Fe) | Balance |
Note: Higher manganese content (4-6%) helps stabilize the austenite phase while reducing nickel content.
| Property | Value |
|---|---|
| Tensile Strength | ≥ 650 MPa (94 ksi) |
| Yield Strength (0.2% offset) | ≥ 450 MPa (65 ksi) |
| Elongation | ≥ 25% |
| Hardness (HB) | ≤ 290 |
| Density | 7.8 g/cm³ |
PREN = %Cr + 3.3 × %Mo + 16 × %N
UNS S32101 PREN Range: 26 – 30
| Grade | Type | Yield Strength (MPa) | PREN | Nickel Content | Relative Cost | Best For |
|---|---|---|---|---|---|---|
| 316L | Austenitic | ≥ 170 | 24 – 26 | 10 – 14% | Medium | Mild corrosive environments |
| UNS S32101 | Lean Duplex | ≥ 450 | 26 – 30 | 1.35 – 1.70% | Low | General industrial, structural, brackish water |
| 2205 / S31803 | Standard Duplex | ≥ 450 | 30 – 38 | 4.5 – 6.5% | Medium-High | Chemical, marine, oil & gas |
Why choose S32101?
Lower cost – Due to reduced nickel and molybdenum content
Price stability – Less exposure to nickel price fluctuations
High strength – Same yield strength as 2205 at lower cost
Good weldability – No preheating, easier fabrication
| Standard | Description |
|---|---|
