Tariku Metals stands out as a top-notch manufacturer and supplier of high-quality Stainless Steel 904L Flat Bars, proudly based in Addis Ababa, Ethiopia. The company has built a solid reputation for providing corrosion-resistant and durable stainless steel products that align with global industrial standards. Thanks to their advanced production capabilities and rigorous quality assurance processes, Tariku Metals delivers materials that are engineered for exceptional performance, even in the toughest environments. Their Stainless Steel 904L Flat Bars cater to various industries, including chemical processing, marine, oil and gas, and construction, offering unmatched strength, weldability, and longevity for critical industrial and structural applications.
Stainless Steel 904L Flat Bar is a high-alloy austenitic stainless steel primarily made of iron, with key additions of chromium (19–23%), nickel (23–28%), molybdenum (4–5%), and copper (1–2%), along with trace amounts of carbon, silicon, and manganese. This unique blend gives it remarkable resistance to strong reducing acids and chloride attack. On the mechanical side, it boasts a tensile strength of about 490–710 MPa, high toughness, and excellent formability. The low carbon content of the alloy ensures superior weldability and minimizes the risk of intergranular corrosion, making it perfect for heavy-duty industrial applications.

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.
Tariku Metals’ Stainless Steel 904L Flat Bars find their way into a variety of demanding applications. In the chemical and petrochemical sectors, they are essential for heat exchangers, process equipment, and storage tanks that handle corrosive substances. The marine industry counts on them for seawater components and shipbuilding, thanks to their outstanding resistance to chloride corrosion. In construction and architecture, these bars are favored for structural frameworks and decorative elements that require long-lasting durability. Moreover, they are utilized in oil refineries, paper mills, and pharmaceutical equipment, where high purity and corrosion resistance are absolutely critical.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
