What is the EN 10025-3 S460NL Standard?

The EN 10025-3 S460NL standard specifies a high-strength structural steel with a minimum yield strength of 460 MPa for plates up to 16 mm thick. Its designation breaks down as:

  • S: Structural steel.
  • 460: Minimum yield strength in MPa.
  • NL: Normalized or normalized rolled, tested for impact toughness at -50°C.

This standard ensures a fine-grain microstructure for superior strength, toughness, and weldability, making EN 10025-3 S460NL ideal for cold environments. Compared to en 10025 3 s355nl normalized structural steel plate, S460NL offers higher strength for heavier structural demands.
