EN 10025 is the European standard for hot-rolled structural steel plates used across engineering, construction, and infrastructure projects. At Hindustan Steel Corporation, we supply the complete range of EN 10025 grades including S235JR, S275JR, S355JR, S355J2, S355K2, and more—each suited for specific load-bearing, welding, and mechanical performance requirements. These steel plates form the backbone of fabrication projects across Europe, the Middle East, and Asia due to their excellent weldability, strength-to-weight ratio, and consistent performance under stress. Whether you’re working on bridges, PEBs, towers, or offshore structures, EN 10025 grades offer standardized reliability backed by mechanical accuracy and chemical balance.
What Are EN 10025 Steel Plates Used For?
EN 10025 plates are structural-grade carbon manganese steel plates used in various industries, such as:
- Civil & Structural Construction – Beams, columns, girders, footbridges, and load-bearing components
- PEB & Warehouses – Fabrication of sheds, trusses, and lightweight buildings
- Telecom & Transmission Towers – Ideal for lattice structures and angle fabrication
- Marine Structures – Suitable for low-temperature and dynamic environments
- Storage & Processing Units – Medium-pressure equipment, tanks, and structural shells
- Transport & Trailers – Chassis frames, platforms, and frames
Their adaptability in bending, forming, welding, and machining makes EN 10025 grades a staple across engineering disciplines.
Key Mechanical Properties to Evaluate
When selecting structural plates, assess the following:
- Yield Strength (MPa) – Ability to resist permanent deformation
- Tensile Strength (MPa) – Maximum stress before breakage
- Elongation (%) – Ductility/flexibility
- Impact Strength – Toughness under shock load
- Hardness – Resistance to wear and tear
- Thickness Tolerance – Accuracy for tight fabrication
Mechanical Properties of EN 10025 Grades (S235, S275, S355)
| Grade | Yield Strength (MPa) | Tensile Strength (MPa) | Elongation (%) |
|---|---|---|---|
| S235JR | ≥ 235 | 360–510 | ≥ 26 |
| S275JR | ≥ 275 | 370–530 | ≥ 23 |
| S355JR | ≥ 355 | 470–630 | ≥ 22 |
| S355J2 | ≥ 355 | 470–630 | ≥ 22 (impact tested at -20°C) |
| S355K2 | ≥ 355 | 470–630 | ≥ 22 (impact tested at -40°C) |
These values provide reliable guidelines for structural design, compliance, and application planning.
Chemical Composition of EN 10025 Structural Plates
| Element | S235JR (%) | S275JR (%) | S355JR (%) |
|---|---|---|---|
| Carbon (C) | ≤ 0.17 | ≤ 0.21 | ≤ 0.24 |
| Manganese (Mn) | ≤ 1.40 | ≤ 1.50 | ≤ 1.60 |
| Phosphorus (P) | ≤ 0.035 | ≤ 0.035 | ≤ 0.035 |
| Sulphur (S) | ≤ 0.035 | ≤ 0.035 | ≤ 0.035 |
| Nitrogen (N) | ≤ 0.012 | ≤ 0.012 | ≤ 0.012 |
Higher-grade variants like S355J2 and S355K2 may contain alloying elements or stricter composition controls to support toughness at sub-zero temperatures.
Understanding EN 10025-2 to EN 10025-6 – Full Series Breakdown
