Neil Metals stands out as a top manufacturer and supplier of Stainless Steel 317 Square Bars and Rods, proudly based in Kolkata, India. These bars are crafted for high-performance use in tough environments where corrosion and high temperatures are a concern. They deliver exceptional strength, great workability, and impressive resistance to chemical attacks. Adhering to ASTM A276 and other relevant standards, our SS 317 square bars and rods come in various sizes and finishes to meet a wide range of industrial requirements. Renowned for their precision, durability, and resistance to corrosion, Neil Metals’ products find their place in industries like petrochemicals, food processing, marine, and pharmaceuticals.
Stainless Steel 317 is an austenitic alloy made up of chromium, nickel, and molybdenum, featuring a composition of 18–20% chromium, 11–15% nickel, and 3–4% molybdenum. This unique blend significantly boosts its resistance to pitting and crevice corrosion. With a tensile strength of around 515 MPa, yield strength of 205 MPa, and an elongation of 35%, it offers remarkable mechanical stability. Compared to standard 304 and 316 grades, SS 317 square bars and rods provide superior corrosion resistance, especially in acidic and chloride-rich environments, making them perfect for demanding industrial applications.
