What is S355ML Density and Weight?

S355ML under EN 10025-4:2004 (2019) is a TMCP weldable fine-grain structural steel with a consistent density of 7.85 g/cm³ (7850 kg/m³ or 490 lb/ft³). This value is standard for low-alloy steels and remains stable across temperature ranges used in structural applications.

Weight calculation formula: Weight (kg) = Length (m) × Width (m) × Thickness (m) × 7850

Example:

• 10 m × 2 m × 0.05 m plate = 7,850 kg (17,300 lb)
• 12 m × 2.5 m × 0.1 m plate = 23,550 kg (51,920 lb)

S355ML’s density, combined with its 355 MPa yield strength and –50 °C toughness, allows 15–20% weight reduction compared to S355J2 while maintaining the same material volume efficiency.

Summary

S355ML EN 10025-4 steel has a density of 7.85 g/cm³, enabling accurate weight calculations: Weight (kg) = L × W × T × 7850. This consistent density, paired with 355 MPa yield and –50 °C toughness, supports 15–20% weight reduction vs S355J2. Gangsteel stocks all thicknesses with verified data sheets.

 

FAQ

Q1: What is the exact density of S355ML?

A: 7.85 g/cm³ (7850 kg/m³), verified on every heat per ISO 1183-1. Use this for all weight and buoyancy calculations.

Q2: How much does a 12m x 2.5m x 50mm S355ML plate weigh?

A: 12 × 2.5 × 0.05 × 7850 = 11,775 kg (25,960 lb).

Q3: Is density the same as S355J2?

A: Yes – both are 7.85 g/cm³. The weight saving comes from using thinner S355ML due to better thick-plate properties.

Q4: Do you provide weight calculators?

A: Yes – contact us for our Excel weight tool or online calculator.

Q5: Delivery time to the U.S.?

A: 7–12 days to major ports (Houston, LA, NY).
