The 2019 revision of the standard introduced a new naming system for steel grades, making it easier to identify the specific properties. The system generally follows the pattern SxxxYLO , and the meaning of each part is key to understanding a grade's capabilities:

The transition from EN 10225:2009 to Part 1:2019 introduced several critical updates:

Ultrasonic testing (UT) is mandatory for EN 10225-1 plates to scan for internal laminations, inclusions, or voids before the steel leaves the mill. Applications of EN 10225-1 Plates

Ana opened her laptop and, without drama, showed photos of the Keldhaven pier, side-by-side with Henrik’s notes and the standard clauses he had used. She told the story of a town that had trusted a code and survived a storm because engineers treated the standard as a guideline to protect people, not a box to tick. Silence filled the room.

: Through-thickness testing is now mandatory for materials starting at 15 mm (previously 25 mm).

– EN 10225-1 specifies requirements for thermomechanically rolled (TM) and normalized (N) steel plates for offshore structures, including chemical composition, mechanical properties, and toughness grades (S355, S420, etc.).

Steel must be manufactured using electric furnace or oxygen processes, typically followed by vacuum degassing. The steel must be in a fully killed condition, fine-grained, and often processed via thermo-mechanical control process (TMCP) or quenching and tempering (Q&T) to achieve the desired mechanical properties. 2.
