Isis Metals is a well-respected manufacturer and supplier of Stainless Steel 317L Hollow Bars based in Manila, Philippines. They pride themselves on delivering high-quality stainless steel products that are designed for exceptional corrosion resistance, durability, and strength. These hollow bars are crafted with precision using cutting-edge technology and rigorous quality controls to meet international standards. Specifically engineered to thrive in harsh environments where they encounter chemicals, acids, and chlorides, Stainless Steel 317L Hollow Bars are essential for industries like chemical processing, marine, food, and pharmaceuticals, providing dependable solutions that guarantee long-lasting performance, excellent machinability, and robust resistance to corrosion and oxidation.
Stainless Steel 317L Hollow Bars are made up of chromium (18–20%), nickel (11–15%), and molybdenum (3–4%), featuring low carbon content that boosts weldability and helps prevent intergranular corrosion. They showcase a tensile strength of about 515 MPa and a yield strength of roughly 205 MPa, along with impressive elongation and toughness. The high molybdenum content offers outstanding resistance to pitting and crevice corrosion, especially in chloride-rich settings. These 317L Hollow Bars also maintain excellent mechanical stability at elevated temperatures, striking a perfect balance between strength, ductility, and corrosion resistance for demanding industrial 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 Bars find extensive use in various industries that demand superior corrosion resistance and mechanical strength. They are particularly suited for chemical and petrochemical processing, marine applications, heat exchangers, paper and pulp industries, and pharmaceutical equipment. Additionally, these hollow bars are employed in condensers, pressure vessels, and piping systems that are exposed to aggressive chemicals and high temperatures. The low carbon content helps reduce carbide precipitation during welding, ensuring long-lasting reliability in critical applications.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
