Weldability is defined via:
: Typically denotes steel intended for use in less critical applications or with standard testing requirements. en 102251 pdf
Perhaps the most defining characteristic of EN 10225 is its rigorous requirement for impact toughness. Steel becomes brittle in cold temperatures. Since offshore structures operate in freezing waters (such as the North Sea), the steel must possess high ductility to prevent brittle fracture. EN 10225 specifies testing temperatures and energy absorption requirements that are far more stringent than onshore standards. It ensures the steel can arrest a propagating crack rather than allowing it to shatter the structure.
It is important to note that EN 10225 explicitly does apply to materials used for subsea pipelines, risers, process equipment, or process piping, as those are governed by different standards. Search engines show results for "en 102251 pdf"
This is the most referenced part of the standard. It specifies requirements for weldable structural steels in the form of plates to be used in fixed offshore structures.
In its older iterations (such as EN 10225:2009), the standard integrated all product forms into a single document. The active to streamline technical requirements: Weldable Structural Steels for Offshore | PDF - Scribd Since offshore structures operate in freezing waters (such
The main goal of EN 10251 is to ensure that suppliers and manufacturers of magnetic circuits have a common, reliable methodology for measuring physical dimensions and shape defects that can affect the performance and stackability of electrical steel laminations.
