Marzouk Steel, located in Tunis, Tunisia, has built a solid reputation as a reliable manufacturer and supplier of top-notch steel products, with a particular focus on ASTM A513 Tubing. Renowned for its precision, durability, and rigorous quality control, Marzouk Steel provides tubing that adheres to international standards and meets various industrial needs. Their ASTM A513 Tubing is designed to deliver outstanding mechanical strength, consistent performance, and excellent weldability. By employing cutting-edge manufacturing techniques, Marzouk Steel guarantees that each tube is built for long-term reliability, making it perfect for automotive, construction, furniture, and industrial applications where strength, accuracy, and resistance to corrosion are crucial for structural and mechanical projects.
ASTM A513 Tubing primarily consists of low to medium-carbon steel with a carefully controlled carbon content, along with manganese, phosphorus, sulfur, and trace elements that boost its strength and durability. Mechanically, it showcases a tensile strength range of 415–620 MPa (60–90 ksi) and a yield strength of 250–350 MPa, along with good elongation and toughness. The tubing is known for its excellent weldability, machinability, and uniformity, making it ideal for structural, mechanical, and fabrication applications that demand consistent performance under load and stress. These characteristics ensure reliability and longevity in both industrial and commercial projects.
