DIN 17100 St37-2 Steel Plate | St37-2 Structural Steel
What is DIN 17100 St37-2 Steel Plate?
As a professional steel plate supplier and China Mill-Direct Exporter, SHH STEEL is pleased to present DIN 17100 St37-2 Steel Plate.
St37-2 is a non-alloy structural steel under the former German standard DIN 17100. It provides a minimum yield strength of 235 MPa (for thickness ≤ 16 mm) and a tensile strength range of 360–510 MPa. Although DIN 17100 has been largely superseded by EN 10025-2, St37-2 remains widely requested in many markets due to its long-standing use and excellent cost-performance ratio. It is essentially equivalent to modern S235JR.
This grade belongs to the DIN 17100 Steel Plate series. SHH STEEL supplies St37-2 as Mill Direct Supply, sourcing directly from major Chinese steel mills. This ensures competitive mill pricing, consistent quality, shorter lead times and full traceability. We offer thicknesses from 6 mm to 150 mm, 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 or equivalent).

Tolerances
Dimensional tolerances for St37-2 steel plate follow DIN standards or equivalent international standards (EN 10029 / ASTM A6).
- Thickness, width and length tolerances according to the ordered class.
- Flatness according to applicable standard.
- Edge conditions: Mill edge or cut edge (flame / plasma).
Tighter tolerances can be provided upon request.
Weldability
St37-2 has excellent weldability due to its low carbon content. It can be welded by all conventional methods (SMAW, GMAW, FCAW, SAW) without special difficulties.
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 under normal conditions.
