The company, famous for its technical accuracy and quality adherence, provides high-performance carbon steel tubes that conform to both European and global standards. ST 52 tube, for example, is widely sought after for its high strength, toughness, and machinability. Irfan Pipes and Tubes ensures that every product satisfies rigorous quality standards, and as a result, it is a reliable supplier for construction, automotive, machine, and hydraulic system applications in international markets.
ST 52 tubing is a high-strength, low-alloy carbon steel grade with a typical chemical composition of around 0.22% carbon, 1.60% manganese, and trace amounts of phosphorus and sulfur. This composition offers a robust balance of weldability, machinability, and structural integrity. ST 52 has tensile strength of between 600 and 800 MPa with a yield strength of approximately 355 MPa, exhibiting good elongation and impact toughness. The material can also be normalized or stress-relieved for improved mechanical properties and is particularly suitable for applications involving strength under dynamic loading and moderate pressures.
