Quantity
The DIN W.Nr.1.4301 WN Flange is a high-performance forged weld neck flange engineered to meet the rigorous demands of modern industrial pipeline systems. Manufactured from premium SS304 (equivalent to 1.4301) stainless steel, this flange offers an optimal balance of corrosion resistance, mechanical strength, and long-term reliability. Designed with a Raised Face (RF) and a 2-inch nominal size in 300LB pressure class, this component is precision-crafted to ensure leak-tight connections in critical service conditions.
Material & Compliance
Crafted from high-quality DIN W.Nr.1.4301 austenitic stainless steel, this flange provides excellent resistance to atmospheric corrosion, organic acids, and alkaline solutions. The material complies with EN 10088 and ASTM A182 standards, ensuring full traceability and international acceptance. The SS304 composition guarantees stable performance across a wide temperature range, making it a trusted choice for systems requiring hygienic or contamination-free operation.

Design Features & Engineering Advantages
- Weld Neck (WN) Design: The tapered hub design reduces stress concentration at the flange-to-pipe joint, distributing mechanical loads evenly. This geometry enhances structural integrity under cyclic thermal and pressure fluctuations.
- Raised Face (RF) Finish: The RF profile concentrates gasket compression, significantly improving sealing efficiency. It accommodates standard spiral wound, PTFE, or graphite gaskets, ensuring minimal leakage even in volatile services.
- Forged Process Method: Utilizing hot die forging, the flange achieves a dense, uniform grain structure—free from porosity or inclusions. This process endows the flange with strong stiffness, high impact toughness, and resistance to deformation under extreme loads.
- Dimensional Accuracy: Manufactured strictly per DIN (Deutsches Institut für Normung) standards, the flange ensures interchangeability and hassle-free installation with mating components.

Performance Characteristics
- Exceptional Sealing Performance: The combination of RF finish and precision-machined gasket contact surface guarantees reliable sealing, even in systems with high-vibration or thermal cycling.
- High Pressure & Temperature Tolerance: Rated for 300LB (PN50 equivalent), this flange operates reliably in pressures up to 50 bar (depending on temperature) and withstands continuous service from -29°C to +650°C (derating applies at elevated temperatures).
- Corrosion Durability: The passive chromium-oxide layer on SS304 provides lasting protection against oxidation and mild chemical attack, reducing maintenance frequency.
