What is EN 10025-3 S460N?

EN 10025-3 S460N is a high-strength structural steel under the EN 10025-3:2019 standard, with a minimum yield strength of 460 MPa for plates up to 16 mm thick. Its designation, also known as material number 1.8901, 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’s strength, toughness, and weldability, making it ideal for moderate climates. Compared to en 10025 3 s355n normalized structural steel plate, S460N offers higher strength for heavier structural demands.
