SS 316L Flanges

SS 316L Flanges are critical mechanical forgings used to connect pipes, valves, pumps, and other equipment to form a piping system. They allow for easy disassembly and maintenance. The "L" designation signifies low carbon content (maximum 0.03%), which is the key feature making them the preferred choice for welded connections. The low carbon level prevents sensitization (intergranular corrosion) during welding, thus preserving the material's excellent corrosion resistance. This corrosion resistance is attributed to the inclusion of Molybdenum (2-3%), providing superior defense against pitting and crevice corrosion in harsh, chloride-rich environments like marine and chemical processing plants. Zeron Fasteners manufactures and supplies a comprehensive range of high-quality SS 316L Flanges, including Weld Neck, Slip-On, Blind, and Lap Joint types, all conforming to standards like ASME B16.5 and ASTM A182 F316L.
