Properties

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 R_eH (N/mm²)		245
Tensile strength R_m (N/mm²)		360 - 450
Elongation %

^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.

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 5000 mm:

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

Flatness

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