Quantity
The DIN W.Nr.1.4306 WN Flange is a high-performance forged flange manufactured from premium SS304L stainless steel, corresponding to material number 1.4306 under the DIN standard. This grade is equivalent to AISI 304L and is characterized by its lower carbon content compared to standard 304, which significantly enhances resistance to intergranular corrosion—particularly critical after welding operations . The flange is produced by Yancheng, a trusted manufacturer in the industrial flange sector.
The Weld Neck (WN) design features a tapered hub that matches the pipe's inside diameter, ensuring unrestricted flow, eliminating turbulence, and reducing erosion . The Raised Face (RF) configuration provides a concentrated sealing surface that enhances gasket compression and joint integrity.
Material Advantages
SS304L (W.Nr.1.4306) offers exceptional corrosion resistance in environments involving water, weak organic and inorganic acids, and is generally resistant down to pH values of approximately 4.5 in low-chloride aggressive media . The low-carbon variant provides superior performance in welded assemblies where intergranular corrosion is a concern.
