What is S460 N Steel?

S460 N 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, 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 S460 N steel’s strength, toughness, and weldability, making it ideal for moderate climates. Compared to en 10025 3 s355n normalized structural steel plate, S460 N offers higher strength for heavier structural demands.

Chemical Composition of S460 N Steel

Gangsteel ensures S460 N steel 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 toughness, a core S460 N 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, 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.

Mechanical Properties of S460 N Steel

Gangsteel guarantees S460 N steel’s mechanical properties excel in 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 ensures durability under high tensile forces.
• Elongation: ≥17% supports complex structural designs.
• Impact Toughness: ≥27 J at -20°C ensures reliability in moderate climates, outperforming en 10025 3 s355n normalized structural steel plate.
• Hardness: Typically 170-210 HB (Brinell), balancing machinability and durability.
