Neil Metals is a well-respected manufacturer and supplier of Stainless Steel 317 Hollow Bars, located in Kolkata, India. They specialize in providing high-performance stainless steel solutions tailored for industries that operate in tough, corrosive environments. Renowned for their precision manufacturing and commitment to quality, Neil Metals offers SS 317 hollow bars that adhere to international standards, ensuring excellent resistance to chemical attacks, particularly in chloride-rich and acidic conditions. These hollow bars find extensive use in sectors like chemical processing, marine, paper, and textiles. With state-of-the-art production facilities and a focus on customer satisfaction, Neil Metals guarantees timely deliveries and consistent quality for both domestic and international clients.
Stainless Steel 317 Hollow Bars are made up of 18–20% chromium, 11–15% nickel, and 3–4% molybdenum, featuring low carbon content to boost corrosion resistance. The increased molybdenum content provides enhanced protection against pitting, crevice corrosion, and sulfuric acid environments, making it superior to SS 316. SS 317 boasts a tensile strength of about 515 MPa and a yield strength of around 205 MPa. Its austenitic structure allows for excellent weldability, formability, and high-temperature strength, while the hollow design helps reduce weight and material usage in structural and pressure-containing applications.

SS 317 offers superior corrosion resistance compared to standard stainless steels like SS 304 and SS 316, especially in chloride-rich environments. It provides enhanced protection against pitting, crevice corrosion, and general corrosion, making it ideal for harsh chemical and marine applications.
SS 317 Hollow Bars typically contain 18-20% chromium, 3-4% molybdenum, 13-15% nickel, with small amounts of manganese, silicon, and carbon. This composition provides excellent corrosion resistance, particularly against chlorides, and enhances its strength at high temperatures.
Stainless Steel 317 Hollow Bars are perfect for applications that demand both corrosion resistance and lightweight properties without sacrificing strength. They are commonly used in chemical and petrochemical plants, pulp and paper mills, textile dyeing and finishing equipment, and marine applications that face saltwater and harsh chemicals. The hollow structure makes them ideal for machining into components like shafts, rollers, and fittings. Additionally, SS 317 hollow bars are favored in heat exchanger tubing, condensers, and pharmaceutical process systems due to their outstanding resistance to chemical attacks and ease of fabrication.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
