EN 10025-4 S275ML Steel Plate | S275ML Fine Grain Structural Steel
What is EN 10025-4 S275ML Steel Plate?
As a professional steel plate supplier and China Mill-Direct Exporter, SHH STEEL is pleased to present EN 10025-4 S275ML Steel Plate (Material Number: 1.8819).
S275ML is a thermomechanically rolled (TMCP) weldable fine-grain structural steel under the European standard EN 10025-4. It provides a minimum yield strength of 275 MPa (for thickness ≤ 16 mm) and is impact tested at –50°C with a minimum energy of 27 J. Compared with S275M, S275ML offers superior low-temperature toughness, making it suitable for structural applications 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 S275ML steel plate in thicknesses from 6 mm to 120 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).

Tighter tolerances can be provided upon request.
Weldability
S275ML has excellent weldability due to its low carbon content, low carbon equivalent and fine-grain structure achieved by thermomechanical rolling. It can be welded by all conventional methods (SMAW, GMAW, FCAW, SAW) with minimal preheating requirements.
Recommended welding consumables:
| Welding Process | Recommended Consumables |
|---|---|
| SMAW (Stick) | E7018, E7016 |
| GMAW (MIG/MAG) | ER70S-6 |
| FCAW | E71T-1 |
| SAW | EM12K + suitable flux |
Preheating is generally not required for thin and medium thicknesses. Low-hydrogen consumables are recommended for thicker plates or critical low-temperature applications.
