^1. Upper yield strength or 0.2% proof stress applies.
^2. For thicknesses > 16 mm, the R_eH 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	S275JR
C	Max.	0.21
Mn	Max.	1.50
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.

 

Tolerances on thickness

Tata Steel can supply to full thickness tolerance specified in EN 10051:2010.

Tolerances  in mm for wide strip and slit wide strip
The tolerances for wide strip and slit wide strip comply with standard EN 10051:2010.

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.

Edge camber

The deviation from the edge over a length of 5000mm:

• with mill edges, no more than 20mm
• with trimmed edges, no more than 15mm

Flatness

Requirements as regards flatness can be agreed at the time of enquiry.
