What is S355N Steel?

S355N is a normalized or normalized rolled fine-grain structural steel under EN 10025-3:2019, with:

• S: Structural steel.
• 355: Minimum yield strength of 355 MPa (≤16 mm).
• N: Normalized, with impact toughness tested at -20°C.
• Material Number: 1.0545.

Its fine-grain microstructure ensures high strength, toughness, and weldability, ideal for moderate climates. Compared to en 10025 3 s460n normalized structural steel plate, S355N has lower strength (355 MPa vs 460 MPa) but is more cost-effective for general structural applications.

S355N Steel Density

The density of S355N steel is 7.85 g/cm³ (7850 kg/m³), typical for structural steels due to its iron-based composition with low-alloy elements. This density is consistent across thicknesses and matches other EN 10025-3 grades like en 10025 3 s420n normalized structural steel plate and en 10025 3 s355nl normalized structural steel plate.

Factors Affecting Density

• Composition: S355N’s low-alloy content (e.g., manganese, niobium) has minimal impact on density, as iron dominates (~97%).
• Consistency: Density remains stable across plate sizes (6–200 mm) and processing conditions (normalized or normalized rolled).

S355N Steel Weight Calculation

The weight of an S355N steel plate is calculated using the formula:
Weight (kg) = Length (m) × Width (m) × Thickness (m) × Density (kg/m³)

Example Calculations

1. Plate: 6 m × 2 m × 10 mm (0.01 m)
   Weight = 6 × 2 × 0.01 × 7850 = 942 kg
2. Plate: 12 m × 3 m × 50 mm (0.05 m)
   Weight = 12 × 3 × 0.05 × 7850 = 14,130 kg
3. Plate: 8 m × 2.5 m × 20 mm (0.02 m)
   Weight = 8 × 2.5 × 0.02 × 7850 = 3,140 kg

These calculations aid in structural design, load-bearing assessments, and logistics planning. For precise project-specific weights, Gangsteel can provide tailored calculations based on custom dimensions.

Chemical Composition Supporting S355N Density

The S355N steel density is influenced by its chemical composition, per EN 10025-3:

Carbon Equivalent (CEV): ≤0.43% (≤63 mm), calculated as CEV = C + Mn/6 + (Cr + Mo + V)/5 + (Ni + Cu)/15, ensuring weldability. The iron-heavy composition (~97%) drives the 7.85 g/cm³ density, consistent with en 10025 3 s275n normalized structural steel plate.
