EN 10219 S275J2H PIPE
EN 10219 S275J2H pipe is a structural hollow steel pipe used in many engineering and construction applications. “S275J2H” indicates a specific grade in this standard. It is made from non-alloy steel by cold forming and welding. It is available in 3 common shapes:round pipe(CHS), square pipe(SHS) and rectangular pipe(RHS).
We offer EN 10219 S275J2H pipe in wide wall thicknesses and OD. We produce them in standard lengths, as well as custom lengths. The production adheres to strict dimensional tolerances to ensure consistency and reliability. In addition, we offer bare, oiled or coated surface treatments to prevent corrosion during transport and storage.
More Information About EN 10219 S275J2H Steel Grade
This European standard only allows for the use of weldable steel. EN 1011-1 and EN 1011-2 specify the critical parameters for the welding of the products covered by this European standard.
While welding these materials, the primary worry is the development of cold cracking in the welded zone as the product’s thickness, strength level, and CEV grows. Cold cracking happens for a variety of reasons:
- Enhanced diffusible hydrogen concentrations in the weld metal;
- Brittle structure in the heat-affected zone;
- High tensile stress concentrations in the welded joint
