Overview of S460N and S460NL

S460N (EN 10025-3)

S460N is a normalized or normalized rolled fine-grain structural steel with:

• S: Structural steel.
• 460: Minimum yield strength of 460 MPa (≤16 mm).
• N: Normalized, with impact toughness tested at -20°C.

It’s suited for moderate climates, offering high strength for applications like building frameworks and bridges.

S460NL (EN 10025-3)

S460NL is a normalized fine-grain structural steel with:

• S: Structural steel.
• 460: Minimum yield strength of 460 MPa (≤16 mm).
• NL: Normalized, with impact toughness tested at -50°C.

S460NL excels in cold climates, making it ideal for offshore platforms and arctic structures, similar to en 10025 3 s420nl normalized structural steel plate.

Chemical Composition Comparison

The EN 10025-3 S460N vs S460NL comparison shows nearly identical compositions, with slight differences in impurities:

Carbon Equivalent (CEV):

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

Key Difference: S460NL has lower phosphorus (0.025% vs 0.030%) and sulfur (0.020% vs 0.025%), enhancing toughness and weldability for colder conditions, aligning with en 10025 3 s355nl normalized structural steel plate.

Mechanical Properties Comparison

EN 10025-3 S460N vs S460NL mechanical properties differ mainly in toughness testing temperature:

• Strength: Both grades share identical yield (460 MPa) and tensile strengths (540-720 MPa) for similar thicknesses, ensuring comparable load-bearing capacity.
• Toughness: S460NL’s -50°C impact testing (≥27 J) makes it superior for sub-zero climates, while S460N’s -20°C testing suits milder conditions, similar to en 10025 3 s355n normalized structural steel plate.
• Hardness: Both have similar hardness (170-210 HB), supporting machinability.
• Thickness Range: Both support up to 200 mm, with S460NL preferred for cold environments.

Welding and Heat Treatment

• S460N: CEV ≤0.48% supports GMAW or SAW (EN 1011-2). Preheating (100-150°C) for >20 mm; PWHT optional (550-650°C). Consumables: ER70S-6 (GMAW), EM12K flux with EH14 wire (SAW).
• S460NL: Identical CEV (≤0.48%), but lower sulfur/phosphorus reduces weld imperfections. Same welding parameters and consumables.

Key Difference: S460NL’s lower impurities offer a slight edge in weld quality for cold climates, aligning with en 10025 3 s420n normalized structural steel plate.

Applications

• S460N:
  • Building frameworks in temperate climates.
  • Bridges and machinery in moderate conditions.
  • General structural applications where cost matters.
• S460NL:
  • Offshore platforms in cold marine environments (e.g., Arctic seas).
  • Wind towers in sub-zero climates (e.g., northern Europe).
  • Bridges and cranes in arctic regions.
