Kunj Sheets and Plates is a leading manufacturer and supplier of **Stainless Steel 317 Sheets and Plates** in Chennai, India. SS 317 is a molybdenum-bearing austenitic stainless steel that offers superior corrosion resistance, especially in acidic and chloride-rich environments. Designed for more aggressive conditions than standard 316, SS 317 provides enhanced strength, excellent weldability, and resistance to pitting and crevice corrosion. At Kunj, we supply high-quality 317 sheets and plates in various sizes, thicknesses, and finishes, tailored to meet the rigorous demands of industries such as chemical processing, pulp and paper, pharmaceuticals, and marine engineering.
Stainless Steel 317 Sheets and Plates** contain approximately 18–20% chromium, 11–15% nickel, and 3–4% molybdenum. This composition significantly improves resistance to chemical attack and pitting. The alloy provides a tensile strength of around 515 MPa and a yield strength of about 205 MPa, with good elongation and toughness. SS 317 maintains structural integrity under high temperatures and corrosive conditions, making it suitable for heavy-duty fabrication. The increased molybdenum content enhances performance in acidic environments and under exposure to chlorides, while its austenitic structure ensures good formability and welding characteristics.
