With a commitment to precision and customer satisfaction, Rupal Metals caters to a diverse array of industries such as chemical processing, marine, pharmaceuticals, and pulp & paper, delivering dependable products tailored to meet rigorous operational needs.
Stainless Steel 317 Hollow Bar is an austenitic stainless steel alloy that boasts a high molybdenum content, which significantly boosts its resistance to pitting and crevice corrosion. Its typical makeup features 18–20% chromium, 11–15% nickel, 3–4% molybdenum, and a low carbon content (≤ 0.08%). This alloy provides enhanced strength and corrosion resistance compared to 316 stainless steel. It has a tensile strength of around 515 MPa, a yield strength of 205 MPa, and an elongation of about 35%. The alloy is non-magnetic, offers excellent formability and weldability, and retains its mechanical integrity even under moderately high temperatures and aggressive chemical 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 Bar finds extensive use in environments that are subjected to harsh chemicals, acids, and chlorides. It’s particularly well-suited for chemical and petrochemical processing equipment, heat exchangers, evaporators, condensers, and marine components. Industries such as pulp and paper, textile processing, and food processing depend on 317 hollow bars for their strength and corrosion resistance. The hollow design not only reduces weight but also ensures high mechanical performance, making it ideal for structural applications and fluid transport.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
