Zusammenfassung:	The present invention relates to a gas generator pipe of an airbag module, the gas generator pipe consisting of a steel alloy with a martensitic matrix. The gas generator pipe is characterized in that the gas generator pipe has a tensile strength, Rm, of at least 1,100 MPa, and the steel alloy has the following alloying elements apart from iron and melt-related impurities in mass percent (Ma %):C 0.05-0.18%Si 0.4-2.6%Mn 0.2-1.4 %Cr 2.0-4.0%Mo 0.05-1.0%N
