Key Advantages
- Corrosion Resistance: 30% higher than F51 duplex steel, 5× higher than 316L stainless steel.
- High Strength: 800 MPa tensile strength allows for thinner wall designs, reducing system weight.
- Cost Efficiency: ~50% cheaper than Hastelloy C-276 with lower lifecycle costs.
- Reliability: Forged as a single piece, eliminating welding seam defects and reinforcement plate welding risks.
Material (F53 Duplex Stainless Steel)
ASTM A182 F53: A super duplex stainless steel (UNS S32750) material standard containing 25% chromium, 7% nickel, 4% molybdenum, and 0.3% nitrogen, with a PREN ≥40, offering superior corrosion resistance compared to standard duplex steels such as F51.
| Property | Specification / Description |
| Corrosion Resistance | Resistant to seawater, chlorides, H₂S/CO₂ acidic environments, pitting, and crevice corrosion (PREN ≥40). |
| Mechanical Strength | Tensile strength ≥800 MPa, hardness ≤290 HB (2.5× stronger than 316L stainless steel). |
| Temperature Range | -50°C to +300°C (continuous use), up to +350°C (short-term exposure). |
Typical Applications
- Marine Engineering: High-pressure seawater desalination pumps, deep-sea oil & gas pipeline branches.
- Oil & Gas: Sour service (H₂S partial pressure >0.1 psi) gathering & transportation systems.
- Chemical Industry: Brine, hydrochloric acid (≤20% concentration) transport pipelines.
- Energy Sector: High-chloride geothermal power generation systems.

Selection & Installation Guide
Selection Criteria:
- Service Medium: Required when chloride concentration >3% or H₂S partial pressure >0.1 psi.
- Temperature & Pressure: Ensure compatibility with Class rating (≤300°C continuous use).
- Alternative Option: Use F51 in mild corrosion environments to reduce costs.
Installation Guidelines:
Welding Process:
- Filler Metal: AWS A5.14 ER2594.
- Heat Input: 0.5–1.5 kJ/mm (excessive heat causes sigma phase precipitation).
- Interpass Temperature: ≤150°C, no preheating required.
Surface Treatment:
- Pickling & Passivation: Complies with ASTM A380.
- Electropolishing: Ra ≤0.4μm for hygienic applications.

FAQ
- F53 has higher chromium (25% vs 22%) and molybdenum (4% vs 3%), with PREN ≥40, offering 30% better corrosion resistance at ~30% higher cost.
- Control welding heat input, ensure rapid post-weld cooling, and avoid 600–900°C temperature range.
MSS SP-97 A182 F53 Outlet Fittings are the ultimate solution for extreme corrosion environments such as deep-sea and sour oil & gas fields. With a super duplex stainless steel composition, they strike the perfect balance between strength and corrosion resistance. Proper selection, welding, and testing ensure optimal performance and long service life.
