Mourad Metals stands out as a top-notch manufacturer and supplier located in Tunis, Tunisia, with a focus on high-quality Stainless Steel 321H Hollow Bars. They offer hollow bars that boast precise dimensions, a fantastic surface finish, and impressive mechanical properties. With state-of-the-art manufacturing facilities and a talented team, Mourad Metals caters to both local and global markets. Their commitment to consistent quality, on-time delivery, and competitive pricing has earned them a reputation as a reliable partner for industries that need durable stainless steel solutions, including chemical processing, aerospace, automotive, and high-temperature engineering.
Stainless Steel 321H Hollow Bars are crafted from a titanium-stabilized austenitic stainless steel alloy, featuring 17–19% chromium, 9–13% nickel, and a higher carbon content compared to standard 321. This extra carbon boosts high-temperature strength and creep resistance, while titanium helps prevent carbide precipitation and intergranular corrosion. In terms of mechanics, 321H hollow bars deliver excellent tensile and yield strength, along with good ductility and toughness, ensuring stability even in elevated temperature settings. These characteristics make them perfect for critical and long-term applications.

SS 304 Hollow Bar offers excellent corrosion resistance, superior to carbon steel but lower than SS 316. It's effective in mildly corrosive environments, such as atmospheric, food processing, and water systems.
SS 304 Hollow Bars are produced through extrusion, drawing, and machining. These processes refine the material's structure, enhancing strength, ductility, and surface finish, ensuring optimal mechanical properties for various applications.
You’ll find Stainless Steel 321H Hollow Bars widely utilized in industries that demand corrosion resistance, high-temperature performance, and structural reliability. Common uses include furnace tubes, heat exchangers, chemical processing equipment, pressure vessels, turbine components, and automotive exhaust systems. They’re also found in aerospace, petrochemical, and power generation sectors where thermal stress and oxidation are significant concerns. The combination of strength, durability, and thermal stability makes 321H hollow bars an ideal 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.
