Chung Metal provides high-quality Stainless Steel 317L Hollow Bars from Da Nang, Vietnam, designed for applications demanding optimal corrosion resistance in harsh environments. 317L is a low-carbon, high-molybdenum stainless steel with increased resistance to chemical attack. Chung Metal delivers tight tolerance, uniform mechanical properties, and excellent surface finish for application in demanding industries such as chemical processing, pollution control, and pulp & paper. Our 317L hollow bars can be supplied in different sizes and lengths to suit high-requirement project needs.
Stainless Steel 317L has 18–20% chromium, 11–15% nickel, and 3–4% molybdenum content, with ≤ 0.03% carbon. It provides better pitting and crevice corrosion resistance compared to 316L. The tensile strength is ~500–620 MPa, yield strength is 170–275 MPa, and elongation is ≥ 40%. It is non-magnetic in the annealed state and resists high chemical and thermal stress in structure. Low carbon content increases weldability and minimizes sensitization.

The low carbon content of SS 317L reduces the risk of carbide precipitation at high temperatures, preventing grain boundary corrosion. This enhances its stability, weldability, and overall performance, making it more reliable in high-temperature environments, especially in corrosive conditions.
SS 317L Hollow Bars offer excellent corrosion resistance, particularly against chlorides and acidic environments, making them ideal for marine and chemical processing industries. Their high strength, durability, and resistance to pitting and crevice corrosion ensure long-lasting performance in harsh conditions.
Stainless Steel 317L Hollow Bars are applied in severe chemical processing operations using sulfuric, acetic, and formic acids. Petrochemical, textile, paper & pulp, and pollution control industries depend on 317L due to its corrosion strength and mechanical stability. 317L is applied in evaporators, tanks, process piping, heat exchangers, and reactors. It has low carbon and resistance to localized corrosion, making it suitable for welded applications in corrosive acidic environments. Its durability also makes it useful for marine and desalination equipment.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
