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