More Information About EN 10219 S275J0H Steel Grade
This European standard specifies weldable steel. EN 1011-1 and EN 1011-2 provide the essential specifications for welding items covered by this European standard.
The greatest concern while welding these materials is the development of cold cracking in the welded zone as the thickness, strength level, and CEV of the product increase. Cold cracking occurs as a result of the following factors:
- Enhanced diffusible hydrogen concentrations in the weld metal;
- Brittle structure in the heat-affected zone;
- High tensile stress concentrations in the welded joint
