EN 10219-s355j2h steel pipe
TUSPIPE’s EN 10219 standard steel pipes are certified and meet the requirements of the EN 10219 standard in terms of material, dimensional tolerances, chemical composition, and mechanical properties.
EN 10219
Les European Norm EN 10219 regulates requirements for cold-formed welded structural pipes made of non-alloy and fine-grain steels without heat treatment. These requirements include dimensions, shapes, delivery conditions, and permissible deviations from dimensional and form tolerances, as well as mechanical property requirements. The standard applies to welded pipes used for the construction of steel structures and for the general purpose of civil engineering, including pipework for the transportation of fluid and other media. This standard also applies to welded pipes used in the construction of pipelines for the transportation of fluids such as oil, gas, and water. The standard is also applicable to welded pipes used in the construction of process piping, power piping, and ductwork. Part 1 includes the technical delivery conditions of EN 10219 structural pipes, and part 2 specifies the tolerance, dimensions and sectional properties of these pipes.
Steel Grade of EN 10219
Below is the steel grade of EN 10219 – S235JRH/ S275J2H/ S355J2H/ S275J0H/ S355J0H/ S355K2H. for TUSPIPE, quality is greater than everything. About the naming rules of steel grade, there are also examples to explain, so that you can better choose the products you need, if you have any questions you can contact us!
S235JRH
Limite d'élasticité : min. 235 MPa Application: Commonly used for structural and mechanical components with good weldability and formability. Impact Toughness: There is no specific impact toughness requirement for this grade.
S275J0H
Limite d'élasticité : Minimum 275 MPa Scope of application: Compared to S235JRH, it has higher strength and is suitable for structures subjected to higher loads. Impact Toughness: J0 indicates guaranteed impact performance at 0°C.
S275J2H
Limite d'élasticité : Minimum 275 MPa
Range of application: Same strength as S275J0H, but more suitable for low temperatures.
Impact Toughness: J2 indicates guaranteed impact performance at -20°C.
S355J0H
Limite d'élasticité : 355 MPa minimum Application: High-strength steel for structures carrying heavy loads, such as large buildings and projects. Impact toughness: J0 indicates guaranteed impact properties at 0°C.
S355J2H
Limite d'élasticité : Minimum 355 MPa
Range of application: Same strength as S355J0H, but for lower temperature environments.
Impact Toughness: J2 indicates guaranteed impact performance at -20°C.
S355K2H
Yield Strength: Minimum 355 MPa Application: Same strength as S355J0H and S355J2H, but provides higher impact toughness and better minimum impact energy. Impact Toughness: K2 indicates a higher guaranteed impact performance at -20°C.

Weldability of EN 10219 Pipe
Weldable steels are specified in this Norme européenne. EN 1011-1 and EN 1011-2 specify the main standards for welding products under this European standard.
When welding these products, the greatest danger is the development of cold cracking in the welded zone as the product thickness, strength level, and CEV rise. Cold cracking is a result of a combination of the following factors:
- elevated diffusible hydrogen levels in the weld metal;
- a brittle structure in the heat-affected zone;
- and large tensile stress concentrations in the welded joint
