ST 52 tubing is a low alloy steel with a high strength structural steel with good weldability and toughening features. Its chemical composition consists normally of carbon (≤ 0.22%), manganese (≤ 1.60%), phosphorus (≤ 0.040%), and sulfur (≤ 0.040%). Mechanically, it offers a tensile strength of approximately 600 N/mm² and yield strength of approximately 355 N/mm², together with elongation of 22% or higher. The high impact resistance and stress durability of the material render it exceptionally well-suited to structural and mechanical applications calling for reliability and resilience.
