Mourad Metals stands out as a leading manufacturer and supplier located in Tunis, Tunisia, with a focus on high-quality Stainless Steel 321H Flat Bars. The company prides itself on delivering flat bars that are precision-engineered, featuring an exceptional surface finish, precise dimensions, and remarkable mechanical properties. Thanks to its state-of-the-art manufacturing facilities and a talented workforce, Mourad Metals caters to both local and international markets. Their commitment to quality, prompt delivery, and competitive pricing has made them a reliable supplier for industries that need robust stainless steel solutions, such as chemical processing, aerospace, automotive, and high-temperature engineering applications.
Stainless Steel 321H Flat Bars are crafted from a titanium-stabilized austenitic stainless steel alloy, which includes 17–19% chromium and 9–13% nickel, along with a higher carbon content compared to standard 321. This extra carbon enhances high-temperature strength and creep resistance. In terms of mechanical properties, 321H flat bars showcase impressive tensile and yield strength, good toughness, and ductility, all while offering excellent resistance to intergranular corrosion and thermal fatigue. These characteristics make them perfect for long-term use in high-temperature settings.

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.
These Stainless Steel 321H Flat Bars find extensive use in industries that demand high-temperature performance, corrosion resistance, and structural reliability. Typical applications include components for furnaces, heat exchangers, pressure vessels, chemical processing equipment, turbine parts, and automotive exhaust systems. They are also well-suited for the aerospace, petrochemical, and power generation sectors, where materials face thermal stress and corrosive conditions. The blend of strength, durability, and thermal stability makes 321H flat bars an excellent choice for challenging industrial and engineering applications.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
