Labdhi Metals is a trusted manufacturer, stockist, and exporter of Stainless Steel 317/317L Tube & Pipe, offering premium-quality tubing solutions for highly corrosive and high-temperature environments. These pipes and tubes are engineered to provide excellent corrosion resistance, especially in sulfur-containing and halide-rich media. With cutting-edge manufacturing facilities and a strict quality management system, Labdhi Metals ensures that all its 317/317L products comply with global industry standards.
Stainless Steel 317 is a molybdenum-bearing austenitic stainless steel with higher concentrations of chromium, nickel, and molybdenum than SS 316. This chemical makeup significantly improves its resistance to pitting and crevice corrosion, making it suitable for harsh environments. 317L, the low-carbon variant, enhances resistance to intergranular corrosion after welding and is preferred in welded structures. Labdhi Metals supplies these pipes in seamless, welded, ERW, and fabricated forms with a range of sizes and wall thicknesses.
The SS 317/317L Tube & Pipe offerings from Labdhi Metals are widely used in industries such as chemical processing, food processing, marine, oil and gas, power plants, and pharmaceuticals. These pipes are appreciated for their durability, strength, and resistance to chemical attack. Labdhi Metals maintains a ready stock of different sizes and specifications, ensuring quick delivery and custom fabrication options to meet client-specific needs.
As a well-established exporter, Labdhi Metals serves clients in the USA, UK, Germany, UAE, Saudi Arabia, Qatar, Africa, and Southeast Asia. With ISO certification and a customer-centric approach, the company provides documentation including mill test certificates, third-party inspections, and compliance with ASTM, ASME, DIN, EN, and JIS standards. Packaging is done securely to ensure damage-free international delivery.
