Technical Specifications Of EN10210 S460 LSAW Structural Pipes

S460 structural steel specified in EN10210 is designed for high-strength hollow structural sections used in large engineering projects. The material typically provides a minimum yield strength of about 460 MPa, with tensile strength usually ranging between 540 and 720 MPa. Its controlled chemical composition, generally maintaining carbon content around or below 0.20 percent together with microalloying elements, helps achieve both high strength and good weldability. This balance allows structural components to maintain stability under heavy loads while reducing overall structural weight.

At Huayang Steel Pipe, LSAW pipes meeting EN10210 S460 requirements are manufactured from high-quality thermomechanically rolled steel plates. The JCOE forming process ensures accurate geometry and consistent wall thickness along the entire pipe body. Longitudinal seams are welded using double submerged arc welding to achieve deep penetration and stable metallurgical bonding. Each pipe undergoes comprehensive inspection including ultrasonic testing of the steel plate, weld seam non-destructive examination, and dimensional verification to ensure structural reliability in bridges, large-span buildings, and heavy industrial frameworks.
