Understanding S460NL Steel Mechanical Strength

S460NL steel 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 indicates:

• 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 S460NL steel mechanical properties like yield strength, tensile strength, and toughness, making it perfect for cold environments. Compared to en 10025 3 s355nl normalized structural steel plate, S460NL offers superior strength for heavier structural demands.

Chemical Composition Supporting Mechanical Strength

Gangsteel ensures S460NL steel mechanical properties are supported by a precise chemical composition:

Key Elements:

• Low Carbon: 0.20% max supports toughness and weldability, critical for S460NL steel mechanical properties.
• Manganese: 1.00-1.70% enhances strength for heavy structures.
• Aluminum & Niobium: Refine grains for -50°C toughness.
• Low Sulfur & Phosphorus: Minimize inclusions for weld quality and strength.

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.
