Chuck Metals, based in Pulau Ujong, Singapore, stands out as a trusted manufacturer and supplier of top-notch stainless steel products, including Stainless Steel 317L Rectangular Bars. These bars are specifically designed to offer exceptional corrosion resistance, making them perfect for tough chemical and marine environments. Catering to various industries like pharmaceuticals, pulp and paper, petrochemicals, and water treatment, Chuck Metals delivers high-quality 317L rectangular bars that comply with international standards. With a reputation for timely delivery, technical know-how, and consistent quality, Chuck Metals has earned its place as a reliable name throughout Singapore and Southeast Asia.
Stainless Steel 317L Rectangular Bars are low-carbon austenitic stainless steels, featuring a composition of chromium (18–20%), nickel (11–15%), molybdenum (3–4%), and a maximum carbon content of 0.03%. The low carbon content enhances weldability and minimizes the risk of intergranular corrosion, while the molybdenum boosts resistance to pitting and chemical attacks. These bars boast a tensile strength of about 75 ksi (515 MPa), a yield strength close to 30 ksi (205 MPa), and an elongation of roughly 35–40%, ensuring they maintain structural integrity and durability even in challenging environments.

Choose Stainless Steel 317L Rectangular Bars based on the level of corrosion resistance needed for your application and the material’s strength requirements. Consider factors like temperature, pressure, and the potential for exposure to harsh chemicals or marine environments.
Stainless Steel 317L Rectangular Bars generally do not require additional corrosion protection coatings due to their inherent resistance to corrosion, especially in acidic and chloride environments. However, in highly aggressive conditions, coatings may be considered for extra protection.
When selecting Stainless Steel 317L Rectangular Bars, consider factors like corrosion resistance in aggressive environments and required mechanical properties such as strength and weldability. Also, evaluate the specific application conditions, including temperature and chemical exposure.
Stainless Steel 317L Rectangular Bars find extensive use in structural and load-bearing applications across chemical processing, marine installations, pulp digesters, and pollution control systems. Their flat design makes them perfect for creating frames, brackets, supports, and components that come into contact with corrosive materials. With their outstanding resistance to chlorides and sulfates, 317L bars promise a long service life and lower maintenance needs. Industries that demand reliability in harsh conditions turn to 317L rectangular bars for their impressive performance, strength, and corrosion resistance.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
