1.8680 (DIN EN 10225-4 : 2019-11) S650MLHCO 1.8680 DIN EN 10225-4 : 2019-11 Supersedes DIN EN 10225 : 2009-10 Valid Germany 1.1.1 1)
1) Remark: Cold finished welded hollow sections of weldable structural steels for the manufacture of fixed offshore structures. The steel according to this standard is not used for the manufacture of subsea pipelines, risers, process equipment, pipe systems and other facilities and equipment. The standard applies primarily to the North Sea area, but may be applied to other areas provided that local conditions, e.g. design temperature, are sufficiently taken into account.
