S355JR and S355J2H Round Seamless Steel Tubes for Structural Applications

1. Product Description:

S355JR and S355J2H Round Seamless Steel Tubes are engineered for structural applications that require high strength and ductility. These tubes are manufactured from low alloy steel and are seamless, ensuring uniform wall thickness and superior structural integrity. The S355 designation indicates the minimum yield strength of 355 MPa, while the JR and J2H grades denote varying levels of impact resistance.

2. Product Features:

  • Seamless Construction: Provides consistent wall thickness and enhanced resistance to pressure.
  • High Yield Strength: Offers a minimum yield strength of 355 MPa for robust structural support.
  • Impact Resistance: J2H grade has enhanced impact resistance for use in colder environments.
  • Weldability: Suitable for welding, facilitating easy integration into structural frameworks.
  • Corrosion Resistance: Offers resistance to atmospheric corrosion for extended service life.
