Louis Metals is a trusted manufacturer and supplier of Stainless Steel 317 Rectangular Bars in Houston, USA, offering high-quality stainless steel products engineered for superior corrosion resistance and mechanical performance. Known for precision and reliability, Louis Metals produces SS 317 rectangular bars using premium raw materials and advanced manufacturing techniques. These bars are designed to perform in highly corrosive environments, especially those involving acids, salts, and chlorides. With enhanced resistance to chemical attack and exceptional strength, Stainless Steel 317 rectangular bars are widely used across chemical processing, marine, and industrial sectors that demand long-term durability and stability.
Stainless Steel 317 Rectangular Bars are high-alloy austenitic stainless steels composed of Chromium (18–20%), Nickel (11–15%), Molybdenum (3–4%), and Carbon (up to 0.08%). The higher molybdenum content significantly improves resistance to pitting, crevice corrosion, and general chemical attack compared to standard austenitic grades. These bars offer a tensile strength of 515–760 MPa, yield strength around 205 MPa, and good ductility and toughness. SS 317 maintains its corrosion resistance and strength even under elevated temperatures and is non-magnetic in the annealed condition, making it suitable for welding and fabrication.

Stainless Steel 317 Rectangular Bars are widely used in industries such as chemical and petrochemical processing, pulp and paper, textile, power generation, and marine environments. Typical applications include chemical tanks, heat exchangers, evaporators, pulp bleaching equipment, and flue gas scrubbers. Due to its superior corrosion resistance, SS 317 is ideal for use in environments with sulfuric acid, chlorides, and other harsh chemicals. These bars are also employed in pharmaceutical processing, desalination plants, and food production equipment, where hygiene, strength, and corrosion resistance are critical. Their formability and weldability make them ideal for custom-fabricated systems and components.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
