SAF 2507 (UNS S32750, EN 1.4410) is a super duplex stainless steel characterized by a balanced microstructure of approximately 50% ferrite (α) and 50% austenite (γ). This dual-phase structure combines exceptional strength, superior corrosion resistance, and excellent toughness, making it ideal for demanding industrial applications in aggressive environments136.
Exceptional Corrosion Resistance
PRE (Pitting Resistance Equivalent) > 43: Outstanding resistance to pitting, crevice corrosion, and stress corrosion cracking (SCC) in chloride-rich environments (e.g., seawater, chemical solutions)1710.
Superior to 904L and comparable to 6% Mo super-austenitic grades (e.g., 254SMO)13.
Resists diluted sulfuric/hydrochloric acids and organic acids (e.g., formic, acetic acid)78.
High Mechanical Strength
Yield Strength ≥ 550 MPa, Tensile Strength: 795–1000 MPa (twice the strength of standard austenitic steels like 316L)1810.
Elongation: ≥25%, Hardness: ≤ 310 HB28.
Thermal Stability
Low thermal expansion coefficient and high thermal conductivity410.
Temperature Limit: Prolonged exposure above 570°F (300°C) may reduce toughness; optimal use below this threshold410.
| Element | Cr | Ni | Mo | N | Mn | C ≤ | Si ≤ | Fe |
|---|---|---|---|---|---|---|---|---|
| Content | 24.0–26.0 | 6.0–8.0 | 3.0–4.0 | 0.24–0.32 | ≤1.2 | 0.03 | ≤0.8 | Balance |
| Trace elements: P ≤ 0.035%, S ≤ 0.020%, Cu ≤ 0.50%1410. |
Density: 8.03 g/cm³
Melting Point: 1300–1390°C
Magnetism: Non-magnetic (annealed condition)48.
Stress Corrosion Cracking (SCC): Excellent resistance in chloride environments17.
Intergranular Corrosion: Low carbon content (≤0.03%) minimizes carbide precipitation risks78.
Erosion-Corrosion & Fatigue: High resistance in marine and acidic media110.
Solution Annealing: 1000–1052°C (rapid air/water cooling) to maintain 50/50 α/γ phase balance28.
Welding:
Recommended Filler: ER2594 wire or E2594 electrode28.
Control heat input to avoid detrimental phase formation (e.g., sigma, chi phases)68.
SAF 2507 plates are widely used in:
Oil & Gas: Offshore platforms, heat exchangers, seawater piping, subsea components17.
Chemical Processing: Reactors, pressure vessels, acid-handling equipment38.
Desalination Plants: High-pressure RO systems, seawater pipelines15.
Pollution Control: Flue gas desulfurization (FGD) scrubbers, absorber towers38.
Marine & Structural: Propeller shafts, corrosion-resistant structural parts310.
| Parameter | Range |
|---|---|
| Thickness | 0.3 mm – 350 mm |
| Width | Standard: 1219–1500 mm |
| Surface Finish | 2B, polished, or customized |
| Standards | ASTM A240, ASME SA-182 |
Custom sizes and processing (e.g., cutting, grinding) available189.
Avoid High Temperatures: Prolonged use >300°C degrades toughness410.
Cost Efficiency: Higher initial cost than 2205 duplex steel but cost-effective vs. nickel alloys18.
Certifications: Supplied with mill test reports (MTRs) per ASTM standards89.
Weight Savings: High strength allows thinner sections vs. conventional steels610.
Longevity: Nano-scale Cr-Mo-N segregation at phase boundaries enables self-repairing passive films6.
Extreme Environment Suitability: Validated for 3000m deep-sea pressure and hydrogen-rich conditions6.
