Welcome to Tariku Metals, your trusted partner in Addis Ababa for premium stainless steel solutions. We take pride in supplying and manufacturing the robust Stainless Steel 321H Flat Bar, a product engineered for demanding environments. Known for its exceptional strength and resilience at high temperatures, this flat bar is the ideal choice for industrial projects across Ethiopia that require unwavering reliability and superior performance, backed by our commitment to quality and local expertise.
The composition of Stainless Steel 321H is defined by its chromium-nickel base, specifically stabilized with titanium to prevent harmful carbide precipitation. This deliberate chemistry grants it outstanding resistance to corrosion and oxidation. Mechanically, it is characterized by its higher carbon content, which provides enhanced strength, particularly at elevated temperatures, making it far more capable under thermal stress than standard grades, ensuring long-term structural integrity in challenging conditions.

The primary alloying element in Stainless Steel 321H is titanium (Ti), which stabilizes the steel and prevents carbide precipitation during welding. It also contains chromium (Cr) for corrosion resistance and higher carbon content for increased strength at elevated temperatures.
Stainless Steel 321H is most suitable for high-temperature applications in the range of 427°C to 816°C (800°F to 1500°F). It offers excellent oxidation resistance and stability in these temperatures, making it ideal for heat exchangers and furnace components.
Typical dimensions of a Stainless Steel 321H flat bar range from 3mm to 150mm thickness, 25mm to 600mm width, and up to 6 meters in length. These dimensions vary based on manufacturer specifications and customer requirements.
The primary application for this flat bar is in high-temperature environments, making it indispensable for fabricating components in Ethiopia’s growing power generation, chemical processing, and petroleum refining industries. It’s also perfectly suited for constructing heat exchangers, furnace parts, and high-temperature exhaust systems. Beyond extreme heat, its overall durability makes it a reliable choice for architectural frameworks, industrial machinery, and structural supports where longevity and resistance to corrosive elements are paramount, offering a versatile solution for builders and engineers.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
