What is S355NL Steel?

S355NL is a fine-grain structural steel under EN 10025-3, designed for high strength and low-temperature toughness. Its designation indicates:

• S: Structural steel.
• 355: Minimum yield strength of 355 MPa (≤16 mm).
• NL: Normalized or normalized rolled, with impact toughness tested at -50°C.

The S355NL density and material specs support its use in demanding structural applications.

S355NL Density

The S355NL material density is approximately 7.85 g/cm³ (7850 kg/m³), typical for structural steels with low alloy content. This density is consistent across EN 10025-3 grades like S355NL, S355N, and S420NL, as their compositions are similar. It enables precise weight calculations for structural designs:

• Weight Calculation: Weight (kg) = Density (7850 kg/m³) × Volume (m³).
• Example: A 1 m × 1 m × 10 mm (0.01 m) S355NL plate has a volume of 0.01 m³, weighing 0.01 × 7850 = 78.5 kg.

The consistent S355NL density supports weight optimization in applications like wind towers and bridges.

Chemical Composition of S355NL

The chemical composition underpins S355NL material density and properties:

Carbon Equivalent (CEV): ≤0.43% (≤63 mm), calculated as CEV = C + Mn/6 + (Cr + Mo + V)/5 + (Ni + Cu)/15, ensures excellent weldability. The low alloy content maintains the standard S355NL density of 7.85 g/cm³.

Mechanical Properties of S355NL

The mechanical properties complement the S355NL material density for structural applications:

• Yield Strength: ≥355 MPa (≤16 mm) supports heavy loads.
• Tensile Strength: 470-630 MPa ensures durability.
• Impact Toughness: ≥27 J at -50°C suits cold climates.
• Elongation: ≥22% allows flexibility in design.

Material Specifications
