Customized steel hollow section S690Q high-strength steel pipe welded pipe for marine engineering machinery manufacturing

Material Analysis of S690Q European Elevation Strong Plate

S690Q steel plate is a quenched and tempered high-strength steel plate, with "S" representing its grade as an European standard, and the corresponding national standard is Q690D high-strength structural steel. Used for the manufacturing of key components with low temperature resistance and high strength, construction machinery, mining machinery structures, etc.
Executive standard for S690Q high-strength plate steel pipe:

EN10025-6
Delivery status of S690Q high-strength plate steel hollow section:

Quenching and tempering
Note: Directly quenching and tempering after hot rolling is considered equivalent to conventional quenching and tempering.
Packaging, Marking, and Quality Certificate of S690Q High Strength Pipe
The packaging, marking, and quality certificate of S690Q high-strength pipe should comply with the provisions of GB/T 247.
