Metal Science and Heat Treatment Aims and scope

Conclusions

  1. 1.

    Electrothermal treatment (electrohardening+electrotempering) of complex alloy steel 8Kh4V2S2MF increases the hardness to HRC 65-67.

  2. 2.

    Electrothermal treatment (hardening with holding 20 sec at austenitizing temperature and electrotempering) of ledeburitic steel Kh12M makes it possible to obtain a hardness of HRC 61-63.

  3. 3.

    To obtain a long service life for tools subject to large alternating loads it is expedient to have some amount of retained austenite in the structure.
