Aditya Stainless is a well-respected manufacturer and supplier of Stainless Steel 317 Nuts, providing robust and high-performance fastening solutions right from Kolkata, India. These nuts are celebrated for their outstanding resistance to chemical attacks and corrosion, making them perfect for tough and aggressive environments. Crafted from top-notch raw materials, they meet international standards like ASTM A194 and ASME B18.2.2. Available in various styles such as hex nuts, lock nuts, and flange nuts, Stainless Steel 317 nuts find extensive use in industries like chemical processing, marine, food processing, and pharmaceuticals, where reliability and durability are essential.
Stainless Steel 317 Nuts are made up of about 18–20% chromium, 11–15% nickel, 3–4% molybdenum, and a maximum carbon content of 0.08%. The higher molybdenum content boosts their resistance to pitting, crevice corrosion, and chemical exposure. Typically, these nuts provide a tensile strength of 515 MPa, a yield strength of 205 MPa, and an elongation of 35–40%. Their exceptional corrosion resistance and mechanical strength make them ideal for demanding industrial settings, especially where sulfur compounds, chlorides, and other corrosive substances are present.
