Abstract (en)
[origin: US2023175360A1] The present invention relates to a perforating gun tube, characterized in that the tube is made of a steel alloy comprising, in addition to iron, the following alloying elements, expressed in mass percent:C0.12-0.22%Si0.3-1.0%Mn1.0 - 4%Cr0.5 - 2%Mo0.1 -1%,V0.05 -0.2%Ti0.02 - 0.1% andB0.001 - 0.01%and impurities due to melting, and that the tube has a yield strength, RP0,2 , in the range of 750 to 1100 MPa. In addition, a perforating gun having such a perforating gun tube is described.
