03 / Standard Chemical Composition
EN 10025-2:2019 / S355JR (hot rolled sections). Values are mass percentages (%). Maximum limits are shown by ≤, minimum limits by ≥; ranges are specification limits and Fe is the balance. These are not measured results for a current delivery heat.
| Element / Indicator | Requirement or Range |
|---|---|
| C | ≤0.24 |
| Si | ≤0.55 |
| Mn | ≤1.60 |
| P | ≤0.040 |

| Fe | Balance |
From the ArcelorMittal EN 10025-2:2019 hot rolled section table. Heat analysis, mass %. Nitrogen-binding exceptions and special galvanizing chemistry follow the standard. Do not interchange this section table with another edition / product form used for plate.
04 / Mechanical Properties & Application Limits
| Thickness / Material Condition | Yield Strength Re / Rp0.2 (MPa) | Tensile Strength Rm (MPa) | Elongation After Fracture A (%) |
|---|---|---|---|
| 3≤t≤16 mm | ≥355 | 470–630 | ≥22 |
| 16<t≤40 mm | ≥345 | 470–630 | ≥22 |

| 63<t≤80 mm | ≥325 | 470–630 | ≥20 |
| 80<t≤100 mm | ≥315 | 470–630 | ≥20 |
| 100<t≤140 mm | ≥295 | 450–600 | ≥18 |
Strength in MPa, proportional elongation A in %. Nominal-thickness groups follow public section data. Reference JR impact 27 J / +20°C; sampling and exemptions follow the standard. Structural design determines member, stability and connection capacities.
05 / Inspection, Processing & Quality Checks
- Check EN 10025-2:2019 grade, nominal thickness, delivery condition and heat/batch documents.
- Measure h, b, tw, tf and cut length; check flange slope, web eccentricity, straightness and twist.
- Determine welding procedures from CEV, thickness and restraint. Agree through-thickness properties, UT and actual impact testing before ordering where required.
- Distinguish hot rolled HE sections from fabricated welded H beams; similar appearance does not establish equivalence.
06 / Export Packaging for This Product
| Stage | Recommended Arrangement | Key Considerations |
|---|---|---|
| Section-Separated Bundles | Identify section designation, steel grade, length and heat number separately. | Keep different grades and delivery conditions in separate bundles. |
| Supports & Corner Protection | Protect flanges, leg edges and machined faces; support long sections at multiple points. | Prevent handling twist, local damage and permanent bending. |
| Loading Checks | Plan loading around cut length, bundle weight, forklift points and container-door clearance. | Assess container type and handling arrangements in advance for long or heavy loads. |
Before shipment, cross-check product, grade, heat number, size, piece count, net weight and gross weight against the packing list. Match labels to inspection documents. For solid-wood pallets, dunnage or crates, check destination-country rules; wood subject to ISPM 15 must be treated and marked by an approved provider. Load dry cargo and arrange supports, blocking and securing according to weight and centre of gravity.
