SS 321 Flanges

SS 321 Flanges are essential industrial components used to connect pipes, valves, and equipment, allowing for easy assembly and maintenance. Common types include Weld Neck, Slip-On, and Blind Flanges. These components are forged from Stainless Steel Grade 321, an austenitic alloy stabilized with Titanium. The Titanium prevents the formation of chromium carbides, which ensures the flange maintains its full resistance to intergranular corrosion (weld decay) after welding or prolonged exposure to high operating temperatures (up to 850°C). Zeron Fasteners manufactures and supplies a comprehensive range of robust SS 321 Flanges (often conforming to ASTM A182 F321) that comply with international pressure and dimensional standards (e.g., ASME B16.5). They are indispensable in critical applications like high-temperature gas processing, heat exchangers, and exhaust piping systems where joint integrity and material stability under extreme thermal and corrosive stress are paramount.
