What are S460N and S460NL Steels?

S460N and S460NL are high-strength structural steels under EN 10025-3, with:

• S: Structural steel.
• 460: Minimum yield strength of 460 MPa (≤16 mm).
• N: Normalized, with S460N tested at -20°C and S460NL at -50°C.
• S460N (1.8901): Ideal for moderate climates, offering robust strength and weldability.
• S460NL (1.8903): Enhanced for colder climates with superior low-temperature toughness.

The normalization process refines their grain structure, enhancing strength and weldability. Compared to en 10025 3 s355n normalized structural steel plate, both offer higher strength for heavier structural demands.

Chemical Composition of S460N and S460NL

Gangsteel ensures S460N and S460NL meet EN 10025-3 chemical composition standards:

Carbon Equivalent (CEV):

• S460N: ≤0.48% (≤63 mm).
• S460NL: ≤0.48% (≤63 mm).

S460NL’s lower sulfur (0.020% vs 0.025%) and phosphorus (0.025% vs 0.030%) enhance toughness and weldability, similar to en 10025 3 s420n normalized structural steel plate.

Mechanical Properties of S460N and S460NL

Gangsteel guarantees S460N and S460NL mechanical properties excel in high-strength applications:

• Yield Strength: Both offer 460 MPa, ideal for heavy loads.
• Tensile Strength: 540-720 MPa ensures durability.
• Elongation: ≥17% supports complex designs.
• Impact Toughness: S460N’s ≥27 J at -20°C suits moderate climates; S460NL’s ≥27 J at -50°C excels in cold environments.
