Conclusions

  1. 1.

    The kinetics of austenite decomposition in continuous cooling were studied and thermokinetic curves of 09G2BF and 12G2FR low-pearlite steels were constructed. Alloying of steel with up to 0.005% boron increases the stability of the austenite and provides higher hardenability of the steel.

     
  2. 2.

    Heat treatment of plates of these steels after controlled rolling (interrupted cooling at the specified rate from the temperature of the finish of rolling or of hardening from 920°C 610–640 MPa with satisfactory plasticity and impact strength.
