George Metals, a reputable manufacturer and supplier located in Houston, USA, specializes in high-quality Stainless Steel 317 Hollow Bars designed for tough industrial environments that face corrosive and high-temperature conditions. Renowned for its exceptional resistance to chemical attacks and pitting, SS 317 is an austenitic stainless steel enriched with molybdenum. George Metals guarantees precision-engineered hollow bars that boast tight tolerances, a superb surface finish, and solid mechanical integrity. Their SS 317 Hollow Bars find extensive use in industries such as chemical processing, marine, pulp and paper, and petrochemical, delivering impressive durability, excellent weldability, and cost-effective performance even in harsh operational settings.
Stainless Steel 317 is composed of 18–20% chromium, 11–15% nickel, and 3–4% molybdenum, which significantly boosts its resistance to pitting and crevice corrosion in chloride and acidic environments. This austenitic alloy offers a tensile strength ranging from 515 to 760 MPa and a yield strength of about 205 MPa, while also maintaining good ductility and toughness under thermal and chemical stress. It performs reliably in high-pressure and high-temperature situations, retaining excellent weldability and formability. The mechanical and chemical stability of SS 317 makes it a go-to choice for industries that require strong resistance to aggressive corrosive agents.

Stainless Steel 317 Hollow Bars are extensively utilized in chemical processing, pulp and paper mills, food processing facilities, desalination plants, and marine engineering due to their outstanding corrosion resistance and strength. These bars are perfect for crafting heat exchangers, pressure vessels, pump shafts, condensers, and scrubber systems. In marine and offshore settings, they are essential for components that come into contact with saltwater and acidic conditions. The hollow design not only reduces weight but also maintains structural strength, making them suitable for a variety of demanding applications.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
