SS 420 Weld Neck Flanges

The SS 420 Weld Neck Flange is a specialized forging component characterized by its long tapered hub that is butt-welded to the pipe. This design provides superior structural integrity and stress distribution, making it the ideal choice for severe service, high-pressure, and high-temperature applications. Manufactured from Martensitic Grade 420 Stainless Steel, these flanges are selected for their exceptional hardness and resistance to wear and erosion, properties significantly improved through controlled heat treatment. The connection is made by butt-welding the flange to the pipe, which ensures the highest integrity joint possible, minimizing turbulence and erosion. Zeron Fasteners produces these critical components using advanced forging techniques, guaranteeing a dense material structure and excellent grain flow along the hub. SS 420 Weld Neck Flanges are widely trusted in the petrochemical, oil and gas, and power industries where flange failure could lead to catastrophic consequences.
