What is S460N Steel?

S460N 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 S460N yield strength and weldability, making it ideal for moderate climates. Compared to en 10025 3 s355n normalized structural steel plate, S460N offers higher strength for heavier structural demands.

Chemical Composition Supporting S460N Yield Strength

Gangsteel ensures the S460N yield strength is supported by a precise chemical composition per EN 10025-3:

Carbon Equivalent (CEV): 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.

S460N Yield Strength and Mechanical Properties

Gangsteel guarantees the S460N yield strength and related mechanical properties excel in high-strength applications:

• Yield Strength: Starts at 460 MPa for plates ≤16 mm, ideal for heavy loads in structures like bridges. Decreases to 370 MPa at 200 mm, still robust for thick sections.
• 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.

The high S460N yield strength is driven by manganese (1.00-1.70%) and microalloying elements like vanadium and niobium, which refine the grain structure.
