What is DIN EN 10025 S460N?

DIN EN 10025 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. The term "DIN EN 10025" reflects its historical association with the German DIN standard, now harmonized under the European EN 10025-3. 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 DIN EN 10025 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.

Historical Context

The "DIN" prefix refers to the German Institute for Standardization, which historically defined grades like StE 460 (DIN 17102). With the adoption of EN standards across Europe, DIN EN 10025 S460N replaced older DIN designations, ensuring compliance with modern European norms.

Chemical Composition of DIN EN 10025 S460N

Gangsteel ensures DIN EN 10025 S460N meets EN 10025-3 chemical composition standards for optimal performance:

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.
