EN-Engineering-Product-Hot-Rolled-Structural steel-All grades OverviewTSE
Availability
Structural steel products are available as follows:
- As-rolled (+AR)
- Normalised rolling (+N)
- Suitable for cold forming (C)
- Suitable for post-galvanising (Class 1)
Relationship with standards
Hot-rolled structural steel complies with European standard EN 10025: 2004 and is available in the grades shown in the table below.
If normalised rolling (+N) or cold forming (C) is required, please specify when ordering. In these cases, this should be indicated by adding the relevant letter to the grade at the time of ordering (for example: S355J0C+AR). Cold forming cannot be guaranteed for structural steel that is not specified as cold-formable.

The CE mark
The CE mark is a symbol devised by the European Council to signify that a product meets the conditions of the applicable council directives. These conditions aim to ensure that the product is reliable and safe. Products that are “produced for incorporation in a permanent manner in construction works” fall under the Construction Products Directive. Hot-rolled steels covered by EN 10025: 2004 are used in such “works” and are therefore covered by the directive. For these products, Tata Steel’s test certificates bear the CE mark and Tata Steel has issued a certified Declaration of Performance (DoP). All the structural products produced by Tata Steel in Europe are CE-marked except for S185+AR.

Chemical composition1. Upper yield strength or 0.2% proof stress applies.
2. For thicknesses > 16 mm, the ReH value is decreased by 10 N/mm2.
3. The impact properties of quality JR products are verified only when specified at the time of enquiry or order.
Impact strengths apply to thicknesses > 6 mm and are for standard test pieces only. Please contact us for details.
For the mechanical properties of cold-forming qualities, please consult us.
Tensile tests may be carried out on non-proportional test pieces as specified in EN 10025-1: 2004.
Elongation after fracture A uses test piece length L0 = 80 mm for t < 3 mm. L0 = 5.65√S0 for t ≥ 3 mm.
t – material thickness in mm.
Impact strength
Impact tests can be performed for thicknesses ≥ 6.0 mm. Please contact us for details.
Chemical composition
Structural steel meets the requirements of the cast analysis in the standard, as shown in the table below.
The steel grades supplied by Tata Steel are always fully killed.
Tata Steel does not supply steel with increased copper content.
| Grade | S235JR | |
|---|---|---|
| C | Max. | 0.17 |
| Mn | Max. | 1.40 |
| P | Max. | 0.035 |
| S | Max. | 0.035 |
| Si | Max. | – |
| N | Max. | 0.012 |
| Cu | Max. | 0.55 |
The maximum value for nitrogen does not apply if the chemical composition shows a minimum total aluminium content of 0.020% or if sufficient other nitrogen-binding elements are present.
The nitrogen-binding elements shall be mentioned in the inspection document.
For the chemical composition of cold-forming qualities, please consult us.
The chemical composition of steels suitable for galvanising complies with EN 10025-2: 2004.
All values are in weight%.
Suitability for cold forming
If chemistry suitable for cold forming (+C) is required, this must be specified when the material is ordered.
Cold forming cannot be guaranteed for structural steel that is not specified as cold-formable.
Suitability for galvanising
If chemistry suitable for post-galvanising (Class 1) is required, this must be specified when the material is ordered.

Shape and dimensional tolerances
The specified values for wide strip do not apply to the uncropped ends of the coil (‘head’ and ‘tail’).
The length of these uncropped ends is calculated using the following formula:
length (in metres) = 90/nominal thickness (in mm), with a maximum of 20 metres.
If required, this part of the coil can be removed, however an additional cost may be charged for this.
