EN 10025 Steel Grades – Structural Steel Standards for Modern Engineering

Table of Contents

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:

  1. Civil & Structural Construction – Beams, columns, girders, footbridges, and load-bearing components
  2. PEB & Warehouses – Fabrication of sheds, trusses, and lightweight buildings
  3. Telecom & Transmission Towers – Ideal for lattice structures and angle fabrication
  4. Marine Structures – Suitable for low-temperature and dynamic environments
  5. Storage & Processing Units – Medium-pressure equipment, tanks, and structural shells
  6. 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

The EN 10025 standard is split into multiple parts based on grade type, alloying, and intended application:

  • EN 10025-2 – Non-alloy structural steel (S235JR, S275JR, S355JR, S355J2, etc.)
  • EN 10025-3 – Normalized/normalized rolled fine-grain structural steels (S275N, S355N)
  • EN 10025-4 – Thermomechanical rolled fine-grain structural steels (S355M, S420M)
  • EN 10025-5 – Weathering steels (S355J0WP, S355J2W)
  • EN 10025-6 – High yield Q&T structural steels (S690QL, S890QL, S960QL)

At Hindustan Steel Corporation, we primarily supply EN 10025-2 and EN 10025-6 grades, which are widely used in industrial fabrication and heavy load structures.

Tips for Welding & Fabrication of EN 10025 Plates

EN 10025 plates are known for their excellent weldability and machinability. Follow these practices:

  • Use low hydrogen electrodes or MIG/MAG with matching filler wire.
  • Preheating not mandatory for S235 or S275 unless thickness > 30 mm.
  • Post-weld heat treatment may be needed for S355J2/K2 in critical load applications.
  • Suitable for flame/plasma cutting, bending, CNC drilling.

All grades meet CE marking and welding certificate requirements as per EN 1090.
