Summary:A gas pressure container for an airbag system of a motor vehicle is disclosed having a tube element with a high bursting resistance when internal pressure is being applied. The tube element includes a steel alloy and a first longitudinal portion of the tube element has a tensile strength Rm,11 higher than (>) 800 MPa, a transition temperature Tu,11 of at least −40° C., and an outer circumference U1. The tube element also includes at least one second longitudinal portion and/or additional longitudinal portions, which extend axially from the first longitudinal portion. The second longitudinal portion or the additional longitudinal portions and the first longitudinal portion are formed from a seamless or welded single-piece tube made of a uniform material, and more specifically from a hot-rolled or cold-drawn tube.
