Stainless Steel 317L Hollow Bar is a low-carbon, high-molybdenum austenitic stainless steel crafted for superior corrosion resistance. Its typical composition features 18–20% chromium, 11–15% nickel, 3–4% molybdenum, and a maximum of 0.03% carbon. This alloy excels in resisting chemical attacks, particularly in sulfurous, acidic, and chloride-rich environments. In terms of mechanical properties, it boasts a tensile strength of around 515 MPa, a yield strength of 205 MPa, and impressive elongation properties of about 35%. Additionally, 317L is known for its excellent weldability, formability, and high creep resistance, making it perfect for demanding structural and pressure-bearing applications.

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 Bar finds extensive use in industries that require outstanding corrosion resistance and structural integrity. It’s especially well-suited for chemical and petrochemical processing, pulp and paper production, food and beverage equipment, and marine applications. Thanks to its low carbon content and high molybdenum levels, it’s ideal for heat exchangers, condenser tubes, reactor vessels, and evaporators that are exposed to aggressive chemicals and high temperatures. The hollow design also allows for material savings while maintaining strength and durability.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
