Stainless Steel 317 Pipe Fittings are alloy components particularly engineered for added corrosion resistance in highly aggressive chemical environments. Produced by reliable suppliers such as Devang Fittings in Kolkata, India, these fittings provide added resistance to pitting, crevice attack, and chemical assault, particularly under acidic or chloride-rich environments. With greater molybdenum compared to regular 316, 317 fittings are well suited for applications requiring long-term strength and structural integrity within corrosive process systems.

Grade 317 stainless steel is an austenitic alloy with about 18–20% chromium, 11–15% nickel, and 3–4% molybdenum, which greatly enhances its corrosion resistance compared to lower alloyed types. It possesses a tensile strength of around 515 MPa and yield strength of approximately 205 MPa, in addition to good ductility, weldability, and chemical attack resistance against sulfuric, acetic, and phosphoric acids. The alloy possesses mechanical strength and corrosion resistance in hot as well as cold temperature conditions.
