Chuck Metals stands out as a trusted manufacturer and supplier of Stainless Steel 317L Hollow Bars right here in Singapore, serving the industrial and engineering sectors throughout Pulau Ujong. This particular grade of stainless steel is a low-carbon, molybdenum-rich austenitic type that shines when it comes to resisting corrosion, especially in environments that are acidic or packed with chlorides. Our hollow bars are crafted to meet global standards like ASTM A276 and ASTM A479, guaranteeing top-notch strength, precise dimensions, and a smooth surface finish for even the most demanding applications.
Stainless Steel 317L is made up of about 18–20% chromium, 11–15% nickel, and 3–4% molybdenum, with a lower carbon content that enhances weldability and helps avoid sensitization. It boasts a tensile strength of roughly 515 MPa and a yield strength of around 205 MPa, along with impressive resistance to pitting, crevice corrosion, and chemical attacks, particularly from sulfuric, acetic, and citric acids.

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.
These hollow bars find their way into various applications, including chemical processing equipment, pulp and paper mills, petrochemical plants, desalination systems, and marine components. You’ll often see them used in heat exchanger tubes, condensers, valve components, and structural supports that face harsh corrosive conditions. With their long-lasting durability, Stainless Steel 317L hollow bars are perfect for high-performance environments where corrosion is a critical concern.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
