Louis Metals is a trustable producer and supplier of Stainless Steel 317L Square Bars and Rods in Houston, USA, which is renowned to supply high-performance stainless steel products for application in highly corrosive and industrial environments. The square bars and rods are manufactured with superior-grade raw material and sophisticated technology, ensuring excellence in quality, dimension accuracy, and durability. Stainless Steel 317L has superior pitting resistance, crevice corrosion resistance, and aggressive chemical resistance and is thus suitable for severe applications in chemical processing, marine, and pharmaceutical industries. Louis Metals provides assured supply, competitive prices, and customized solutions for varied engineering requirements.
Stainless Steel 317L Square Bars/Rods are low-carbon austenitic stainless steels with Chromium (18–20%), Nickel (11–15%), Molybdenum (3–4%), and up to 0.03% Carbon maximum. The low carbon avoids sensitisation during welding, and molybdenum improves corrosion resistance, particularly in chloride and acidic conditions. These bars provide tensile strength of 515–760 MPa and yield strength of approximately 205 MPa. SS 317L is non-magnetic in the annealed state and enjoys good ductility, weldability, and mechanical stability under various service conditions, including high temperature and severe chemical exposure.

Stainless Steel 317L Square Bars and Rods are utilized in those applications where there is a need for greater resistance to chemical attack as well as high strength. Typical industries involve chemical processing, pulp and paper, marine, food and beverage, and pharmaceuticals. Usage includes heat exchangers, evaporators, reactors, storage tanks, pump shafts, structural supports, and process piping. SS 317L is especially ideal for sulfuric acid, chlorides, and other severe substances-containing environments. Its square profile offers added strength and load distribution, making it well-suited for frames, braces, and components in heavy-duty industrial and structural applications where performance and corrosion resistance are paramount.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
