EN 10025-3 S460NL Steel Plate | S460NL Fine Grain Structural Steel
What is EN 10025-3 S460NL Steel Plate?
As a professional steel plate supplier and China Mill-Direct Exporter, SHH STEEL is pleased to present EN 10025-3 S460NL Steel Plate (Material Number: 1.8903).
S460NL is a normalized (or normalized rolled) weldable fine-grain structural steel under the European standard EN 10025-3. It provides a minimum yield strength of 460 MPa (for thickness ≤ 16 mm) and is impact tested at –50°C with a minimum energy of 27 J. This is one of the highest strength low-temperature grades in the EN 10025-3 series, combining high load-bearing capacity with excellent toughness in cold environments. SHH STEEL sources this material directly from leading Chinese steel mills, ensuring competitive mill-direct pricing, stable quality and reliable delivery.
We supply S460NL 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).

Weldability
S460NL has moderate-to-good weldability for a high-strength fine-grain structural steel. It can be welded by conventional methods (SMAW, GMAW, FCAW, SAW).
Recommended welding consumables:
| Welding Process | Recommended Consumables |
|---|---|
| SMAW (Stick) | E8018, E7018 |
| GMAW (MIG/MAG) | ER80S-D2, ER70S-6 |
| FCAW | E81T1, E71T-1 |
| SAW | EH14 / EM12K + suitable flux |
Preheating is generally required for thicker plates. Low-hydrogen consumables and strict control of heat input are strongly recommended, especially for low-temperature service.
