EN 10225-1 is part of the European standard series titled "Weldable structural steels for fixed offshore structures - Technical delivery conditions" . Specifically, Part 1 focuses on .
Purchasing steel using the EN 10225-1 standard requires choosing an inspection category. The standard defines rigorous testing regimes, often requiring independent third-party inspection agencies to witness testing.
(Note: The 'G' followed by a number indicates specific delivery conditions such as Normalized (N), Thermomechanical Rolled (M), or Quenched and Tempered (Q).) en 10225-1 pdf
The standard requires steel to demonstrate excellent impact toughness at low temperatures, specifying an impact test temperature down to .
Covers grades such as S355NLO , S420MLO , and higher-strength quenched and tempered grades up to S690QLO . EN 10225-1 is part of the European standard
When thick steel plates are welded, contraction stresses can cause tearing parallel to the plate surface (lamellar tearing). EN 10225-1 specifies Z-testing (Z25 or Z35) to measure the reduction of area in a tension test perpendicular to the plate surface, ensuring internal soundness. 4. Non-Destructive Testing (NDT)
The standard focuses heavily on two critical mechanical properties: yield strength and low-temperature impact toughness. When thick steel plates are welded, contraction stresses
