S460N Steel Specifications

At Gangsteel, we’re excited to dive into the specifications of S460N specifications, which define this high-strength, low-alloy structural steel under EN 10025-3. S460N, known for its robust strength, toughness, and weldability, is ideal for structural applications like bridges, cranes, and building frameworks in moderate climates.

As part of the en 10025 3 normalized steel plate family, S460N offers a minimum yield strength of 460 MPa and -20°C toughness, making it a reliable choice for demanding projects. Gangsteel breaks down the S460N specifications, including chemical composition, mechanical properties, and applications, with comparisons to grades like en 10025 3 s420n normalized structural steel plate and en 10025 3 s355n normalized structural steel plate.

What is S460N Steel?

S460N is a high-strength structural steel under EN 10025-3, 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.
  • N: Normalized or normalized rolled, tested for impact toughness at -20°C.

The normalization process refines the grain structure, enhancing S460N specifications for strength, toughness, and weldability. Compared to en 10025 3 s355n normalized structural steel plate, S460N offers higher strength for heavier structural demands.
