Understanding S460NL Material Properties

S460NL 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 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 the S460NL material properties for toughness and weldability, making it ideal for cold environments. Compared to en 10025 3 s355nl normalized structural steel plate, S460NL offers superior strength for heavier structural demands.

Chemical Composition of S460NL

Gangsteel ensures S460NL material properties are supported by a precise chemical composition optimized for strength and cold-weather performance:

Key Elements Supporting S460NL Material Properties:

• 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 key S460NL material 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.

Mechanical Properties of S460NL

Gangsteel guarantees S460NL material properties deliver top performance for high-strength applications:

• Yield Strength: Starts at 460 MPa for thin plates, ideal for heavy loads in structures like cranes.
• Tensile Strength: 540-720 MPa handles high tensile forces, a core S460NL material property.
• Elongation: ≥17% supports complex structural designs.
• Impact Toughness: ≥27 J at -50°C ensures reliability in cold climates, outperforming en 10025 3 s355n normalized structural steel plate.
• Hardness: Typically 170-210 HB (Brinell), balancing machinability and durability.
