Stainless Steel 317L Rectangular Bars are low-carbon, molybdenum-bearing austenitic stainless steels, typically composed of about 18–20% chromium, 11–15% nickel, 3–4% molybdenum, and a maximum carbon content of 0.03%. This particular grade is known for its superior resistance to pitting, crevice corrosion, and chemical attacks. It boasts a tensile strength of around 515 MPa, a minimum yield strength of 205 MPa, and exceptional elongation and toughness. The low carbon content enhances weldability while reducing the risk of carbide precipitation during welding, making it a fantastic choice for critical applications in corrosive 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.
You’ll find Stainless Steel 317L Rectangular Bars commonly used across various industries, including chemical processing, petrochemical, pharmaceutical, marine, and pulp & paper. These bars are perfect for structural and mechanical applications that demand high resistance to corrosion and chemical attacks. Their outstanding performance in acidic and chloride-rich environments makes them ideal for heat exchangers, tanks, evaporators, and condensers. Plus, 317L rectangular bars are also utilized in food processing, textile equipment, and pollution control systems, thanks to their strength, formability, and resistance to atmospheric corrosion.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
