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, 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 steel properties like strength and weldability, ideal for moderate climates. Compared to en 10025 3 s355n normalized structural steel plate, S460N offers higher strength for heavier structural demands.

Chemical Composition Supporting S460N Steel Properties

Gangsteel ensures S460N steel properties are backed by a precise chemical composition per EN 10025-3:

Carbon Equivalent (CEV): Capped at 0.48% for plates up to 63 mm, calculated as CEV = C + Mn/6 + (Cr + Mo + V)/5 + (Ni + Cu)/15, ensuring weldability, similar to en 10025 3 s420n normalized structural steel plate.
