Aditya Stainless stands out as a reliable manufacturer and supplier of Stainless Steel 317L Nuts based in Kolkata, India. They provide top-notch fasteners designed specifically for tough industrial settings that face corrosive elements and high temperatures. SS 317L is a low-carbon, molybdenum-rich austenitic stainless steel known for its impressive resistance to chemical attacks, especially in acidic and chloride-heavy environments. These nuts find their place in various industries, including chemical processing, pulp and paper, marine, and pharmaceuticals, where strength, durability, and corrosion resistance are absolutely essential. Crafted to comply with international standards like ASTM, ASME, DIN, and ISO, Stainless Steel 317L Nuts are perfect for critical fastening in challenging service conditions.
Stainless Steel 317L Nuts are made up of 18–20% chromium, 11–15% nickel, 3–4% molybdenum, and a low carbon content (≤0.03%), which boosts their corrosion resistance and weldability. They boast a tensile strength ranging from 515 to 620 MPa, a yield strength of about 205 MPa, and an elongation of 35–40%. The molybdenum addition greatly enhances their ability to resist pitting, crevice corrosion, and chemical attacks in acidic settings. The low carbon content helps prevent intergranular corrosion after welding, making these nuts suitable for welded assemblies and environments with high moisture or chloride exposure.
