EN 10025-2 S355J0 Steel Plate | S355J0 Structural Steel
What is EN 10025-2 S355J0 Steel Plate?
As a professional steel plate supplier and China Mill-Direct Exporter, SHH STEEL is pleased to present EN 10025-2 S355J0 Steel Plate (Material Number: 1.0553).
S355J0 is a high-strength non-alloy structural steel under the European standard EN 10025-2. It provides a minimum yield strength of 355 MPa (for thickness ≤ 16 mm) and is impact tested at 0°C with a minimum energy of 27 J. Compared with S355JR, the lower impact test temperature makes S355J0 more suitable for structural applications requiring better toughness in colder environments. SHH STEEL sources this material directly from leading Chinese steel mills, ensuring competitive mill-direct pricing, stable quality and reliable delivery.
We supply S355J0 steel plate in thicknesses from 6 mm to 150 mm (thicker plates available on request), widths up to 3000–4000 mm, and lengths up to 12000–18000 mm. Custom cutting, shot blasting and priming services are available. All plates are delivered with full Mill Test Certificates (EN 10204 3.1).

Delivery Conditions
SHH STEEL, as a China Mill-Direct Supplier, supplies EN 10025-2 S355J0 steel plate mainly in the following conditions:
- +AR (As-rolled) – most common
- +N (Normalized) – available on request
Additional options:
- Shot blasting and shop primer
- Ultrasonic testing (EN 10160)
- Z-direction testing (Z15 / Z25 / Z35)
- Third-party inspection (SGS, BV, TUV, etc.)
Tolerances
Dimensional tolerances for S355J0 steel plate follow EN 10029 (for plates) or EN 10051 (for strips).
- Thickness, width and length tolerances according to the ordered class.
- Flatness according to EN 10029.
- Edge conditions: Mill edge or cut edge (flame / plasma).
Tighter tolerances can be provided upon request.
Weldability
S355J0 has good weldability. It can be welded by conventional methods (SMAW, SAW, GMAW, FCAW, etc.). Due to the higher strength and carbon equivalent, preheating is often recommended for thicker plates. Low-hydrogen consumables are advised for critical applications.
