Conclusions

  1. 1.

    We propose a heat treatment for steels 30KhGSA and 35Kh to improve the plasticity and deformability that consists of quenching from high temperature and reheating to optimal temperature in the intercritical range.

     
  2. 2.

    Slow reheating (∼1 deg/min) to optimal temperature in the intercritical range leads to higher plasticity and lower strength than rapid heating (∼150 deg/min).

     
  3. 3.

    The increase in the plasticity and notch toughness with reheating to optimal temperature in the intercritical range depends on the susceptibility of the steel to structural inheritance.
