Steels for gas containers are a specific category of steels for pressure vessels. These steels are deep drawable and non-ageing.

Steels for gas containers have very good weldability and excellent toughness. Their strength remains constant, even after heat treatment of the welds (normalisation or stress-relief annealing). This property guarantees the safety of the gas containers.

These grades are used for the production of gas containers according to the following process: top and bottom are cold formed, welded (SAW) and normalised.
