Mechanical Properties
Steel for gas cylinders has the following mechanical properties, measured transverse to the rolling direction:
EN 10120: 2008 | Grade | P245NB |
---|---|---|
Min. yield strength1 ReH (N/mm²) | 245 | |
Tensile strength Rm (N/mm²) | 360 - 450 | |
Elongation % | ||
t < 3 | 26 | |
t ≥ 3 | 34 |
1. Upper yield strength or 0.2% proof stress applies.
Elongation after fracture A uses test piece length L0 = 80 mm for t < 3 and L0 = 5.65√S0 for t ≥ 3.
t – material thickness in mm.

Tolerances
Tolerances for wide strip and slit wide strip comply with standard EN 10051: 2010.
Tighter tolerances are available, please contact us.
EN-EngineeringAutomotive-Product-Hot-rolled-All grades Shape and dimensional tolerances TSE
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.
Option for maximum crown values
The following high crown C40 options available for hot-rolled products.
Crown values on the C20-position as well as minimum crown values on both C20 and C40 position are also available on request.
