Mourad Metals stands out as a top-notch manufacturer and supplier located in Tunis, Tunisia, with a focus on high-quality Stainless Steel 321 Flat Bars. They offer flat bars that boast an impressive surface finish, precise dimensions, and dependable mechanical performance. With state-of-the-art manufacturing facilities and a talented team, Mourad Metals serves both local and international markets. Their dedication to maintaining consistent quality, ensuring timely deliveries, and offering competitive prices has earned them a reputation as a reliable partner for industries that need durable, high-performance stainless steel products. This includes sectors like chemical processing, aerospace, automotive, and high-temperature engineering.
Stainless Steel 321 Flat Bars are made from an austenitic stainless steel alloy that contains 17–19% chromium and 9–13% nickel, with titanium added to prevent carbide precipitation. This stabilization not only boosts resistance to intergranular corrosion—especially after welding—but also provides excellent strength at high temperatures. In terms of mechanics, 321 flat bars deliver solid tensile and yield strength, toughness, and ductility. Their thermal stability, paired with corrosion resistance, makes them perfect for critical and high-temperature applications.

The primary alloying element in Stainless Steel 321 is chromium, typically comprising around 17-19%. Chromium provides corrosion resistance, while titanium is added to improve high-temperature stability and prevent carbide precipitation during welding or prolonged exposure to elevated temperatures.
Stainless Steel 321 is most suitable for temperatures ranging from 800°F to 1500°F (427°C to 815°C). It excels in high-temperature environments due to its titanium stabilization, which prevents carbide precipitation and maintains corrosion resistance under prolonged heat exposure.
Typical dimensions of Stainless Steel 321 flat bars vary, with widths ranging from 20 mm to 150 mm, thicknesses between 3 mm and 50 mm, and lengths up to 6 meters, customizable based on specific requirements.
These Stainless Steel 321 Flat Bars find their way into various applications that require high-temperature performance, corrosion resistance, and structural integrity. Common uses include furnace parts, heat exchangers, chemical processing equipment, pressure vessels, aerospace components, automotive exhaust systems, shafts, and fasteners. The blend of mechanical strength, durability, and resistance to thermal fatigue makes 321 flat bars an excellent choice for demanding industrial, engineering, and high-temperature applications.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
