High-quality EN10219 structural non alloy S275J0H rectangular steel tube

EN10219 standard S275J0H rectangular steel tube has carbon content ≤0.18% and manganese content ≤1.50% as the core components, and phosphorus and sulfur content are strictly limited to ≤0.035% to ensure material toughness and weldability. Its yield strength is ≥275MPa, tensile strength is 430-580MPa, 0℃ impact energy is ≥39J, suitable for dynamic load scenarios, and meets the safety requirements of construction and industry through CE certification.

S275J0H rectangular steel tube adopts cold forming process and argon arc welding technology, with an outer diameter tolerance control of ±0.1mm and an oxide layer thickness of ≤ 5μm. Combined with the strict welding quality specifications of EN10219, it is widely used in energy equipment tubelines and power support structures. By optimizing the uniformity of the microstructure through controlled rolling state processing, it combines weather resistance and fatigue resistance, and is suitable for high-precision assembly requirements
