Stainless Steel 904L Flat Bars are made up of significant amounts of chromium (19–23%), nickel (23–28%), along with molybdenum (4–5%) and copper (1–2%). This low-carbon austenitic stainless steel is known for its excellent resistance to reducing acids and chloride stress corrosion cracking. In terms of mechanical properties, these bars boast a tensile strength of about 490–710 MPa and a yield strength of roughly 220 MPa. They are also recognized for their superior weldability and formability, all while maintaining their structural integrity under high-stress conditions. SS 904L flat bars are celebrated for their toughness and durability, even in extremely corrosive and harsh chemical environments.

Stainless Steel 904L Flat Bar is widely used in chemical processing, oil and gas, marine, pharmaceutical, and pulp and paper industries due to its exceptional corrosion resistance, particularly in acidic, chloride-rich, and high-stress environments.
Stainless Steel 904L offers superior corrosion resistance compared to standard austenitic stainless steels, excelling in harsh environments with strong acids (sulfuric, phosphoric) and chloride exposure, due to its high nickel, chromium, and molybdenum content, reducing pitting and stress corrosion.
Yes, Stainless Steel 904L Flat Bar is highly suitable for marine environments due to its excellent resistance to chloride-induced pitting, crevice corrosion, and stress corrosion cracking, making it ideal for shipbuilding, seawater equipment, and coastal structural applications.
These Stainless Steel 904L Flat Bars find extensive use in applications that demand exceptional corrosion resistance and mechanical strength. In the chemical and petrochemical sectors, they are utilized in process equipment, tanks, heat exchangers, and piping systems. The marine industry counts on them for components that are exposed to seawater and salty atmospheres. In pharmaceuticals and food processing, they guarantee hygiene and corrosion-free performance. Additionally, they are employed in pulp and paper processing, pollution control equipment, and flue gas scrubbers. Their remarkable resistance to sulfuric and phosphoric acids makes SS 904L flat bars particularly suitable for highly corrosive environments.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
