What Is Structural High Strength Steel Plate EN 10149?
EN 10149 is a European standard for hot-rolled flat products made of high yield strength steels for cold forming. EN 10149-2 covers steels delivered in the thermomechanically rolled condition, identified by the letters “MC” in the grade name (for example S500MC or S700MC).
- S = Structural steel
- Number = Minimum yield strength in MPa (e.g., 500 MPa for S500MC)
- M = Thermomechanically rolled
- C = Suitable for cold forming
Thermomechanical rolling controls temperature and deformation during rolling. The result is a fine grain structure, high strength with low carbon content, good toughness and easy welding.
Why Choose EN 10149 High Strength Steel Plates?
1. High Strength-to-Weight Ratio
Higher yield strength lets designers use thinner plates for the same load. This reduces dead weight in trailers, trucks and cranes, which saves fuel and transport cost.
2. Excellent Cold Formability
These plates are designed for bending, press-braking, flanging and roll forming without cracking when the correct bend radius is used.
3. Good Weldability
The low carbon and low carbon-equivalent design supports MIG/MAG, TIG and submerged arc welding, with reduced risk of cold cracking compared with conventional quenched steels.
4. Reliable Toughness
EN 10149-2 plates are supplied with impact testing, typically at -20°C, which makes them suitable for demanding structural use.
5. Consistent Quality
Tight control of chemistry and rolling gives uniform mechanical properties from plate to plate.

Welding and Fabrication Tips
Cold Forming
Use a suitable bend radius according to plate thickness and grade. Keep the bend line perpendicular to the rolling direction wherever possible, and finish plate edges smoothly before bending.
Welding
Use low-hydrogen consumables, keep the joint clean and dry, and follow the recommended heat input. Preheat is generally low, but always follow your approved welding procedure (WPS).
Cutting
Plasma, laser and oxy-fuel cutting are all commonly used. Laser and plasma give a cleaner edge for later bending.
How to Choose the Right EN 10149 Grade
