ASTM A182 F22 Forged Fittings Manufacturer and Supplier
Metinox Overseas manufactures and supplies forged fittings in 2.25Cr-1Mo alloy steel (UNS K21590) that meet ASTM A182 F22. We offer socket weld and threaded fittings from Class 3000, 6000 and 9000 LB and sizes available for power plant piping, boiler circuits, fired heater skids. All fittings come with full material traceability, EN 10204 3.1 Mill Test Reports and third party inspection if requested. Critical project needs can be dispatched at an urgent or immediate pace.
Upgrade to ASTM A182 F91 Forged Fittings only when service temperature exceeds the ASME B31.1 allowable stress ceiling for F22. For lower-temperature services where a Cr-Mo alloy is still required, ASTM A182 F11 Forged Fittings offer a cost-effective alternative within the broader Alloy Steel Pipe Fittings range.

Engineers frequently specify the correct chemistry but the wrong product standard. F22 and WP22 share an identical 2.25Cr-1Mo composition, yet they cover entirely different product forms and connection methods. For wrought buttweld fittings in larger bore pipe systems, refer to our ASTM A234 WP22 Pipe Fittings page. The table below clarifies the key differences.
| Parameter | ASTM A182 F22 | ASTM A234 WP22 |
|---|---|---|
| Product Form | Forged fittings | Wrought buttweld fittings |
| Connection Type | Socket weld and threaded | Buttweld (butt-end) |
| Typical Size Range | 1/4 inch to 4 inch (small bore) | 1/2 inch and above (larger bore) |
| Dimensional Standard | ASME B16.11 | ASME B16.9 |
| Chemistry (Cr-Mo) | 1.90-2.60% Cr, 0.87-1.13% Mo | 1.90-2.60% Cr, 0.87-1.13% Mo |
| Raw Material Equivalent | A335 P22 alloy steel pipe | A335 P22 alloy steel pipe |
| ASME Reference | SA182 F22 | SA234 WP22 |

B2B Procurement & Quality Verification Protocols
Every ASTM A182 F22 Class 3 forged fitting shipped from Metinox Overseas undergoes strict verification testing to guarantee reliability in high-temperature creep applications. Our quality processes feature standard testing options:
- Material Verification: Positive Material Identification (PMI) using handheld XRF analysis.
- Volumetric Inspections: 100% Ultrasonic Testing (UT) to identify internal forging voids per ASTM standards.
- Surface Evaluation: Liquid Penetrant Testing (LPT) or Magnetic Particle Testing (MPT) for structural weld preparations.
- Material Documentation: Certified Mill Test Reports issued in full accordance with EN 10204 3.1.

Class 1 is annealed or normalized and tempered, with a minimum tensile of 415 MPa (60 ksi) and is used where ductility during forming is the priority. Class 3 is normalized and tempered, reaching 515 MPa (75 ksi) minimum tensile and 310 MPa (45 ksi) minimum yield, making it the required class for 6000 LB and 9000 LB pressure-class connections per ASME B16.11.
Upgrade to F91 only when service temperature exceeds the allowable stress limit of F22 in ASME B31.1, generally above 593°C (1100°F). F91 adds vanadium and niobium for superior creep resistance in ultra-supercritical boiler circuits. For most subcritical and conventional supercritical plant designs, F22 Class 3 remains the correct and more cost-effective selection.
ASTM A182 F22 forged fittings are manufactured from 1/4 inch to 4 inch NPS in 3000 LB, 6000 LB, and 9000 LB pressure classes per ASME B16.11. Both socket weld and threaded end connections are available across all pressure classes. Class 3 heat treatment is required for 6000 LB and 9000 LB ratings.
Both share the identical 2.25Cr-1Mo chemistry. ASTM A182 F22 covers forged socket weld and threaded fittings for small-bore connections dimensioned to ASME B16.11. ASTM A234 WP22 covers wrought buttweld fittings in larger bore sizes dimensioned to ASME B16.9. Specify A182 F22 for instrument taps and small-bore branches; specify A234 WP22 for main line buttweld elbows and tees.
