Marzouk Steel, based in Tunis, Tunisia, stands out as a leading manufacturer and supplier of top-notch steel products, including Carbon Steel EN 10305-4 Pipes. These pipes are precision-engineered to adhere to rigorous international standards, ensuring exceptional strength, durability, and dimensional accuracy. EN 10305-4 pipes are especially prized in applications that demand high precision, smooth surfaces, and dependable performance. Marzouk Steel employs cutting-edge manufacturing techniques alongside strict quality control measures to deliver robust, long-lasting steel solutions for critical piping systems, both in Tunisia and on the global stage.
The composition of Carbon Steel EN 10305-4 Pipes primarily includes iron, with carefully regulated amounts of carbon, manganese, phosphorus, sulfur, and other elements to boost mechanical performance and weldability. They boast high tensile strength, typically ranging from 360 to 500 MPa, and a minimum yield strength of 235 to 355 MPa, depending on their size and grade. These pipes are cold-drawn or cold-finished, which results in excellent dimensional accuracy, smooth internal and external surfaces, and consistent mechanical properties. Their high weldability and suitability for bending or machining make them versatile for precise engineering applications.
