ST 52 Pipes are high-strength, low-alloy carbon steel pipes that conform to DIN 2391 and DIN 17121 specifications. Known for their excellent weldability, machinability, and impact resistance, these pipes are primarily used in structural and mechanical applications. The material composition includes carbon, manganese, and trace amounts of phosphorus and sulfur, providing a perfect balance of strength, ductility, and toughness. ST 52 pipes are especially suited for load-bearing applications where both strength and formability are essential.
These pipes are typically available in seamless and welded forms, with hot-rolled or cold-drawn surface finishes. ST 52 seamless pipes are manufactured using precision techniques to achieve tight dimensional tolerances, high surface quality, and superior mechanical performance. Common mechanical properties include a minimum yield strength of 355 MPa and tensile strength ranging from 490 to 630 MPa. These characteristics make ST 52 suitable for hydraulic systems, pressure vessels, automotive frames, cranes, bridges, and heavy machinery.
