Labdhi Metals is a reputed manufacturer, stockist, and exporter of high-quality Stainless Steel 317/317L Flanges, offering precision-engineered flange solutions to a wide range of industries across the globe. Known for their superior corrosion resistance and excellent mechanical strength, these flanges are ideal for harsh environments where high-temperature service and exposure to aggressive chemicals are common. Labdhi Metals produces SS 317/317L flanges in various types and pressure classes, tailored to meet international standards and project-specific requirements.
Stainless Steel 317 is a high-alloy, molybdenum-bearing austenitic stainless steel with improved corrosion resistance compared to SS 316, particularly in acidic chloride environments. 317L is the low-carbon version of 317, specifically designed to enhance weldability and reduce the risk of intergranular corrosion after welding. These properties make 317/317L flanges suitable for applications in the chemical processing, petrochemical, marine, food processing, and pharmaceutical industries.
Labdhi Metals offers a wide range of SS 317/317L flange types, including Weld Neck, Slip-On, Blind, Threaded, Socket Weld, Lap Joint, and Long Weld Neck flanges. All flanges are produced using top-grade raw materials and advanced forging and machining techniques to ensure dimensional accuracy, pressure integrity, and durability. Each flange undergoes rigorous quality testing for compliance with standards such as ASME B16.5, B16.47, DIN, and EN.
As a leading stockist, Labdhi Metals maintains a large inventory of Stainless Steel 317/317L Flanges in various sizes (from ½” NB to 48” NB) and pressure ratings (Class 150 to Class 2500). With a well-organized supply chain and strong logistics capabilities, the company ensures timely delivery of both bulk and custom orders. All products are supported by mill test certificates and third-party inspection reports, meeting ASTM and ASME specifications.
