Conclusions

  1. 1.

    A method for determining the critical stress level under the action of electric current pulses has been considered.

  2. 2.

    It has been shown that the limiting state (flow) of 12Kh18N10T and 03Kh13AG19 steels experiencing the action of electric current pulses sets in at stresses exceeding the corresponding yield point values at a temperature of 293°K by factors of 1.84–2.11, which makes it possible to use low-temperature hardening for raising the allowable stress level in structural elements of electric devices made of these steels operating under subzero conditions.
