Conclusions
A C−C−T diagram was plotted for steel 16GFR, which makes it possible to predict with adequate reliability the character of the structure formed during cooling of pipe at given rates under plant conditions and thus to correct the heat-treatment process for pipe made of steel 16GFR with strength σb=720 MPa and guarantee the mechanical properties and cold resistance required.
