S275J2H
TUSPIPE’s S275J2H steel pipes are certified to the EN 10219 S275J2H standard. Third-party certification is available. Our S275J2H steel pipes offer the advantages of high strength and good toughness.
S275J2H
EN 10219 S275J2H Steel tubes are hollow tubes for structural use.
Tensile strengths of Cold-Formed S275J2H Steel Welded Pipe range from 410Mpa to 580Mpa, with a minimum yield strength of 255Mpa. S275J2H tubes are widely used in civil engineering applications such as bridge building, structural frame construction, factory constructions, and mechanical engineering systems.
The symbol J and the letter 2 indicate that the quality has the required impact properties at -20°C, respectively.

Weldability of EN 10219 S275J2H Pipe
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
