SS 317L Tube & WNR. 1.4438 ERW Pipe stockist in India
Stainless Steel 317L Pipes and Tubes are manufactured from low-carbon austenitic stainless steel with high chromium, nickel, and molybdenum content. This composition provides superior resistance to corrosion, especially against chloride pitting and crevice attack. Compared to 316 grade, this alloy offers higher molybdenum content for stronger chemical protection. These pipes show excellent mechanical strength, good elongation properties, and stable performance in aggressive environments. ERAMETS STEEL ALLOYS PVT LTD is a trusted Manufacturer, Supplier, Stockist, and Exporter of Stainless Steel 317L Pipes and Tubes in Mumbai, India, supplying premium quality material at competitive prices.
SS 317L Seamless Pipes are produced from solid billets without any welding joints, offering higher strength and uniform wall thickness. These pipes perform well in high-pressure and corrosive applications such as chemical plants, heat exchangers, and condensers. ASTM A312 TP 317L Seamless Pipes provide excellent dimensional accuracy and smooth internal surfaces for efficient fluid flow. UNS S31703 Welded Pipes and WNR 1.4438 ERW Pipes are manufactured using advanced fusion welding methods and are suitable for structural and industrial piping systems.

The alloy density of Stainless Steel 317L Tubes is approximately 8.0 g/cm³, giving them strong stability under thermal and mechanical stress. These tubes also offer elongation of around 35%, which supports fabrication and forming operations. Their low carbon content improves weldability and reduces the risk of carbide precipitation during welding. Industries prefer 317L Stainless Steel Tubing for power generation, petrochemical processing, pharmaceutical equipment, and marine installations.
Our product range includes ASME SA 312 Grade 317L Round Pipes, AISI 317L Square Pipes, and DIN 1.4438 Rectangular Pipes for different construction and engineering needs. These shapes help in installations where space and alignment are critical. ASTM A312 Gr TP 317L Polished Pipes feature smooth surface finishes that enhance corrosion resistance and improve appearance for exposed piping systems. Polished and cold-rolled pipes are widely used in hygienic and decorative applications.
1.4438 SS 317L Schedule 40 Pipes are suitable for both low-pressure and medium-pressure services. These pipes offer a clean internal bore that minimizes scale formation and supports continuous fluid flow. Their melting point of around 1450°C allows them to perform reliably in high-temperature environments. Available wall thickness ranges from thin gauge tubing to heavy-duty industrial pipes depending on project needs.
All Stainless Steel 317L Pipes and Tubes supplied by ERAMETS STEEL ALLOYS PVT LTD are tested and certified as per ASTM, ASME, DIN, and EN standards. Each batch undergoes chemical composition testing, mechanical strength testing, and dimensional inspection. We provide customized sizes, certified material test reports, safe packaging, and fast delivery across Mumbai and all over India.
