What is S460N Steel?

S460N is a normalized or normalized rolled fine-grain structural steel under EN 10025-3, with:

  • S: Structural steel.
  • 460: Minimum yield strength of 460 MPa (≤16 mm).
  • N: Normalized, with impact toughness tested at -20°C.

Its fine-grain microstructure ensures high strength and weldability, ideal for moderate climates. Compared to en 10025 3 s355n normalized structural steel plate, S460N provides higher strength for heavier structural loads.

 

S460N Equivalent China GB Q460D

The closest S460N equivalent China GB Q460D is Q460D, a high-strength low-alloy steel under GB/T 1591-2018, with -20°C toughness and 460 MPa yield strength. Q460D is widely used in Chinese manufacturing and closely matches S460N for structural applications.

Key similarities:

  • Yield Strength: Both 460 MPa (≤16 mm).
  • Toughness: ≥27 J at -20°C.
  • Weldability: Low CEV for easy fabrication.
