Quantity
The ASTM A182 F304 WN Flange is a premium-grade, forged stainless steel component engineered for demanding piping systems. Manufactured from W.Nr.1.4301, this 1-inch, 300LB weld neck flange combines superior material properties with a robust raised face design to deliver exceptional sealing performance and structural integrity. Produced via a precise hot-forging process in accordance with EN10222-5, this flange exhibits a fine-grain microstructure that enhances its mechanical strength, toughness, and resistance to thermal fatigue.
Key Features & Design Advantages
- Superior Material Composition: Crafted from ASTM A182 F304 (equivalent to 1.4301), this flange offers excellent resistance to oxidation, intergranular corrosion, and general atmospheric corrosion, making it ideal for continuous service at temperatures up to 870°C (in oxidizing conditions).
- Weld Neck Configuration: The tapered hub of the WN flange reduces stress concentration at the weld joint, providing smooth stress transition and high resistance to dishing and deflection under high-pressure loads.
- Raised Face (RF) Sealing: The RF design concentrates gasket pressure over a smaller contact area, ensuring strong stiffness, reliable bolt-load retention, and superior sealing even in fluctuating temperature and pressure cycles.
- Precision Forging: The hot-forged process eliminates porosity and voids, resulting in a dense, uniform grain structure that guarantees exceptional durability and long service life in critical applications.
