High-grade stainless steel 317 tubing made for use in extremely corrosive environments is available from Vinit Stainless, a well-known manufacturer and supplier with headquarters in Chennai, India. Austenitic stainless steel SS 317, which contains molybdenum, offers improved resistance to chemical attack, especially from acids and chlorides. Vinit Stainless follows international standards like ASTM A213 and A269 while producing 317 tubing with precision engineering. These tubes come in a variety of wall thicknesses and diameters in both seamless and welded forms. Our tubing guarantees long-lasting performance and high resistance to pitting and crevice corrosion, making it perfect for industries such as chemical processing, pharmaceuticals, and marine applications.
In order to prevent sensitisation and intergranular corrosion, stainless steel 317 tubing has a low carbon content, 18–20% chromium, 11–15% nickel, and 3–4% molybdenum. Compared to ordinary stainless steels, this composition provides better resistance to chemical attack. It has outstanding elongation and toughness, with a tensile strength of roughly 515–675 MPa and a yield strength of roughly 205 MPa. When exposed to high temperatures and pressures, SS 317 tubing functions effectively, preserving its structural integrity and resistance to corrosion. It is appropriate for demanding industrial and marine applications due to its good formability and weldability.
