Stainless Steel 317L Flanges, classified under UNS S31703 and produced in accordance with ASTM A182 F317L, are among the most sought-after corrosion-resistant flanges used in highly aggressive industrial applications. Adinox Overseas, a leading manufacturer and global exporter of stainless steel flange products, offers premium-grade Stainless Steel 317L Flanges that are engineered to provide superior durability, excellent strength, and exceptional resistance to chemical and pitting corrosion.
The 317L stainless steel alloy is a low-carbon, molybdenum-bearing austenitic stainless steel that is specifically designed for increased resistance to chemical attack, particularly in sulfurous and halide-containing environments. This alloy’s low carbon content makes it suitable for welding without the risk of intergranular corrosion, making ASTM A182 F317L Flanges highly reliable in heat-affected zones. These features are crucial in industries like petrochemical, pharmaceuticals, food processing, paper and pulp, and marine applications.
Adinox Overseas manufactures these flanges using high-quality raw materials, ensuring that every piece complies with international standards like ASTM, ASME, ANSI, DIN, JIS, and EN. The UNS S31703 Flanges are available in a wide range of types such as Slip-On, Weld Neck, Blind, Socket Weld, Lap Joint, and Threaded Flanges, allowing compatibility with varied pipe connection methods. These flanges are not only corrosion-resistant but also capable of withstanding elevated pressures and temperatures, making them ideal for both high-pressure and high-temperature service environments.
Choose Adinox Overseas for your requirements of Stainless Steel 317L Flanges, and benefit from unmatched service, timely delivery, and competitive pricing. Our flanges are trusted by clients worldwide for their reliability and long service life even in the harshest environments.
