Dhruv Metals, a prominent manufacturer and supplier located in Hyderabad, India, specializes in high-quality Stainless Steel 317 Hollow Bars designed for tough industrial settings. Known for its exceptional corrosion resistance and outstanding mechanical strength, SS 317 is perfect for applications that deal with harsh chemicals and extreme temperatures. Dhruv Metals produces hollow bars in a variety of sizes, customized to meet client needs, while strictly following international standards like ASTM A269 and A511. With a strong commitment to product reliability, precision engineering, and timely delivery, the company caters to industries such as chemical processing, marine, power generation, and pharmaceuticals both in India and abroad.
Stainless Steel 317 Hollow Bar is an austenitic stainless steel alloy that contains about 18–20% chromium, 11–15% nickel, and 3–4% molybdenum. This higher molybdenum content enhances its resistance to pitting, crevice corrosion, and chemical attacks in acidic and chloride-rich environments. It boasts a tensile strength of around 515 MPa, a yield strength of about 205 MPa, and an elongation of 35–40%. The alloy is also known for its excellent weldability and formability. SS 317 retains its mechanical integrity even at high temperatures, making it a great choice for hollow components in demanding operating conditions.

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 find extensive use in applications that require resistance to aggressive chemicals and high temperatures. In the chemical and petrochemical sectors, they are ideal for reactor vessels, piping systems, and heat exchangers that come into contact with sulfuric and acetic acids. The pulp and paper industry uses them in bleach washers and digesters. The pharmaceutical and food processing sectors appreciate their hygienic surface and corrosion resistance. In marine applications, they perform well in structural and fluid-handling systems. Additionally, SS 317 hollow bars are utilized in power plants, textile machinery, and pollution control equipment, where both strength and corrosion resistance are crucial.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
