Conclusions

  1. 1.

    The susceptibility to brittle fracture of Kh8 steel pipe at room temperature depends on the heat treatment conditions of the pipe blanks.

  2. 2.

    The resistance to brittle fracture at room temperature is highest after normalization (quenching) and high-temperature tempering, followed by rapid cooling. The cold brittleness threshold is low, the work of crack propagation is high, and the fracture is completely ductile.
