Hot-rolled
Steel for gas cylinders
Tata Steel’s structural steel for gas cylinders offers excellent deep-drawing properties and weldability for ease of processing.
The grades allow for reliable normalising of the welded gas cylinder - retaining strength that contributes to optimal safety in use.

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 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.
