S355J2H Structural ERW Steel Tube
Introduction to S355J2H Structural Resistance Welded Steel Pipe
EN 10210 S355J2H is a hot-rolled hollow structural section manufactured according to the European standard EN 10210. It has a minimum yield strength of 355 MPa (wall thickness not exceeding 16 mm) and excellent toughness at low temperatures, capable of withstanding impacts down to -20°C. This makes it ideal for a wide range of applications in the construction and engineering industries.
Manufacturing Process of EN 10210 S355J2H Steel Pipe: EN 10210 S355J2H steel pipe can be manufactured using seamless or welded processes. Two common welding methods include:
Resistance Welding (ERW): This process uses resistance heating and pressure to weld materials together. It is efficient, suitable for mass production, and applicable to steel pipes of various wall thicknesses and materials.
Submerged arc welding (SAW): Submerged arc welding generates an arc under a layer of granular flux, resulting in deeper penetration and superior weld quality. It is particularly suitable for welding thicker profiles.
