EN10219 S355JR Hollow Steel Section

EN10219 standard is for structural hollow section pipe used for construction pipe, bridge steel pipe, foundation steel pipe. HYSP is professional in EN10219 S355JR Hollow Steel Section manufacturing and exporting. We have customers of EN10219 S355JR Hollow Steel Section in Singapore, Hong Kong, Italy, German etc.

There are lots of technical properties for EN10219 standard, like tensile strength, and weldability. Let’s see the weldability of EN10219 S355JR Hollow Steel Section steel pipes:

The EN10219 S355JR Hollow Steel Section specified in this European Standard are weldable. General requirements for welding the products in accordance with this European Standard are given in EN 1011-1 and EN 1011-2.

NOTE 1 When welding these products, as product thickness, strength level and CEV increase, the occurrence of cold cracking in the welded zone forms the main risk. Cold cracking is caused by a combination of the following factors: 

• 
  high levels of diffusible hydrogen in the weld metal;
  


• 
  a brittle structure in the heat affected zone; 
  


• 
  significant tensile stress concentrations in the welded joint.
  

NOTE 2 By using guidelines, specified for example in EN 1011-1, EN 1011-2 or any other relevant standard, the recommended welding conditions and the various welding ranges for the EN10219 S355JR Hollow Steel Section steel grades can be determined. These will vary depending on the product thickness, the applied welding energy, the design requirements, the electrode efficiency, the welding process and the weld metal properties of EN10219 S355JR Hollow Steel Section.
