What is EN10025 S460NL Steel?

EN10025 S460NL is a high-strength structural steel under EN 10025-3, offering 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.
• NL: Normalized or normalized rolled, tested for impact toughness at -50°C.

The normalization process refines the grain structure, enhancing EN10025 S460NL’s strength, toughness, and weldability, making it perfect for cold environments. Compared to en 10025 3 s355nl normalized structural steel plate, EN10025 S460NL provides superior strength for heavier structural demands.

Chemical Composition of EN10025 S460NL

Gangsteel ensures EN10025 S460NL meets EN 10025-3 chemical composition standards for optimal performance:

Key Elements:

• Low Carbon: 0.20% max ensures clean welds and toughness.
• Manganese: 1.00-1.70% boosts strength for heavy structures.
• Aluminum & Niobium: Refine grains for -50°C toughness, a core EN10025 S460NL specification.
• Low Sulfur & Phosphorus: Minimize inclusions for superior weld quality.

The Carbon Equivalent (CEV) is 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 s420nl normalized structural steel plate.
