    S. Yakovlev, V. Tregubov, S. Yakovlev The changing of mechanical properties of hot-rolled pipes from steel 12hzgnmfba in

    the rotary drawing process The results of theoretical investigations of the changing of mechanical properties of

    hot-rolled pipes from steel 12HZGNMFBA according to deformation level and steady tem-perature after piece tempering in the rotary drawing process are presented.

    Keywords: mechanical properties, rotary drawing, pipe, deformation level, steady temperature, planning of experiments.
