S355J2 designation and selection
S355J2 is a general structural designation whose strength band and impact conditions are governed by the applicable EN product standard. Do not shorten the enquiry to S355 if the approved design calls for J2. Its nominal strength family does not make it equivalent to DH36 or EH36, which follow their own material testing and approval frameworks.
Enquiry fields for EN 10025-2 S355J2
Confirm the exact edition, product form and dimensions, final delivery condition, quantity, equipment duty and accepting authority. Ask the producer for thickness-specific mechanical requirements and the complete heat analysis. If the application is classed, specify the required approval and inspection documents before production.
Certificate review and release
Connect the specified material to the delivered heat and piece IDs, then review the results and final condition. Sampling, test temperature, specimen geometry and any supplementary examination must match the order. Resolve missing evidence before releasing the material for fabrication. A cross-reference handbook is a comparison aid; the applicable standard and accepting engineer determine the final decision.

- Class society requested
Society names are enquiry options. Approval and certificate scope must be confirmed for the actual material.
Frequently asked questions
Is this automatically equivalent to a shipbuilding hull grade?
No. The approved application specification and accepting authority must establish suitability.
