How to Read and Decode EN Steel Grade Names

The EN grade designation is designed to quickly communicate a steel plate's key mechanical properties and delivery condition. This standardized naming convention helps engineers, fabricators and buyers quickly identify the material best suited for their application.

Example: S355J2+N

  • S = Structural steel

  • 355 = Minimum yield strength of 355 MPa

  • J2 = Charpy impact testing at -20°C

  • +N = Normalized or normalized-rolled condition
