Description


ASTM A182 F53 (UNS S32750) Weld Neck Raised Face Flanges | ASME B16.5 Class 150-2500 | Super Duplex



1. Introduction: Premium Super Duplex Solution

ASTM A182 F53 (UNS S32750) Weld Neck Raised Face (WNRF) Flanges deliver exceptional corrosion resistance and 2X higher strength than standard austenitic stainless steels. Manufactured to ASME B16.5/B16.47 standards, these flanges are ideal for aggressive environments in oil/gas, chemical processing, and offshore applications.


2. Chemical Composition (ASTM A182)


Precise alloy balance ensures pitting/crevice corrosion resistance:


Element Min (%) Max (%) Key Role
Chromium 24.0 26.0 Corrosion/Oxidation Res.
Nickel 6.0 8.0 Austenite Stabilizer
Molybdenum 3.0 4.0 Pitting Resistance
Nitrogen 0.24 0.32 Strength & Corrosion Res.
Iron Balance
Matrix
PREN1 ≥ 40
Superior to 316L (PREN 25)


3. Equivalent Grades


Interchangeable specifications for international procurement:


Standard Grade UNS EN (EU) Common Names
ASTM F53 S32750 - Super Duplex 2507
EN 1.4410 S32750 X2CrNiMoN25-7-4 -
Others - - Zeron 100® UR52N+


4. Mechanical Properties (Room Temperature)


Combines high strength with ductility:


Property Value Test Standard
Tensile Strength 800 MPa (min) ASTM A182
Yield Strength (0.2%) 550 MPa (min) ASTM A182
Elongation 15% (min) ASTM A182
Hardness 290 HBW (max) ASTM A182
Impact Toughness ≥ 45 J (-46°C / -50°F) ASTM A370


5. Key Advantages


  • Extreme Chloride Resistance: Withstands sour gas (H₂S), seawater, and acids (HCl, H₂SO₄) better than 316L/904L.


  • High Pressure/Temp Rating: Suitable for ASME Class 2500 (420 bar) and 300°C (570°F) continuous service.


  • Cost Efficiency: 50% thinner sections vs. 316L reduce weight and installation costs.


  • Stress Corrosion Cracking (SCC) Immunity: Critical for chemical processing equipment.


6. Application Areas


Designed for critical services in:


  • Oil & Gas: Subsea manifolds, christmas trees, pipeline risers


  • Chemical: HCl acid reactors, sulfuric acid coolers


  • Desalination: SWRO high-pressure tubing, brine heaters


  • Pollution Control: FGD scrubber modules


  • Marine: Propeller shafts, seawater valves
