What is Steel S460NL?

Steel 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, boosting steel S460NL’s strength, toughness, and weldability, making it ideal for cold environments. Compared to en 10025 3 s355nl normalized structural steel plate, steel S460NL delivers higher strength for heavier structural demands.

Chemical Composition of Steel S460NL

Gangsteel ensures steel S460NL’s chemical composition is optimized for high-strength applications:

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 steel S460NL property.
• Low Sulfur & Phosphorus: Minimize inclusions for superior weld quality.

The Carbon Equivalent (CEV) is capped at 0.48% for plates up to 63 mm, ensuring weldability, similar to en 10025 3 s420nl normalized structural steel plate.
