EN 10219 S355J2H LSAW pipes are commonly used in heavy structural systems where strength, toughness, and dimensional stability are critical under long-term static loads.
Material Properties & Huayang Production Control
S355J2H is a fine-grain structural steel with a minimum yield strength of 355 MPa and tensile strength typically ranging from 470 to 630 MPa. The J2H designation confirms impact toughness tested at −20°C, making it suitable for exposed structural applications. For DN600 dimensions, Huayang adopts LSAW forming to ensure uniform wall thickness and high roundness. Plate chemical composition and carbon equivalent are strictly controlled to maintain good weldability. The longitudinal seam is subjected to 100% ultrasonic testing and radiographic inspection when required. Dimensional tolerance, straightness, and mechanical properties are verified per EN 10219, ensuring reliable performance in large-span buildings, industrial plants, and infrastructure projects.
