Marzouk Steel, based in Tunis, Tunisia, is a trusted manufacturer and supplier of high-quality steel products for pipeline and industrial applications. Among its specialized offerings are Carbon Steel F56 Forged Fittings, engineered for moderate to high-pressure piping systems where enhanced strength and reliability are required. Manufactured in accordance with ASTM A694 standards, these forged fittings are designed to match API 5L X56 pipeline grades. With strict quality control, precision forging, and adherence to international specifications, Marzouk Steel delivers F56 forged fittings that ensure safe operation and long-term service performance.
Carbon Steel F56 Forged Fittings are produced from high-quality carbon steel with controlled chemical composition and micro-alloying elements to improve strength. This grade provides higher yield and tensile strength than F52, along with excellent toughness and resistance to deformation under pressure. The forging process enhances grain structure, while heat treatment ensures uniform mechanical properties, good weldability, and dimensional accuracy. These fittings are suitable for demanding service conditions.
