EN 10025-2 S355JR Steel Plate | S355JR Structural Steel
What is EN 10025-2 S355JR Steel Plate?
As a professional steel plate supplier and China Mill-Direct Exporter, SHH STEEL is pleased to present EN 10025-2 S355JR Steel Plate (Material Number: 1.0045).
S355JR is one of the most popular high-strength non-alloy structural steels under the European standard EN 10025-2. It provides a minimum yield strength of 355 MPa (for thickness ≤ 16 mm) combined with good weldability, formability and toughness. The “JR” designation indicates that the material meets impact requirements of 27 J at +20°C. SHH STEEL sources this material directly from leading Chinese steel mills, ensuring competitive mill-direct pricing, stable quality and reliable delivery.
We supply S355JR 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).

Mechanical Properties
Mechanical properties of EN 10025-2 S355JR (longitudinal direction):
| Thickness (mm) | Yield Strength ReH (min) | Tensile Strength Rm | Elongation A (min) | Impact Energy KV (min) |
|---|---|---|---|---|
| ≤ 16 | 355 MPa | 470 – 630 MPa | 22% | 27 J at +20°C |
| > 16 ≤ 40 | 345 MPa | 470 – 630 MPa | 22% | 27 J at +20°C |
| > 40 ≤ 63 | 335 MPa | 470 – 630 MPa | 21% | 27 J at +20°C |

Delivery Conditions
SHH STEEL, as a China Mill-Direct Supplier, supplies EN 10025-2 S355JR 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 S355JR 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
S355JR has good weldability. It can be welded by conventional methods (SMAW, SAW, GMAW, FCAW, etc.). Due to the higher strength and carbon equivalent compared with S235/S275 grades, preheating is often recommended for thicker plates. Low-hydrogen consumables are advised for critical applications.
