Conclusions

  1. 1.

    Heavy-load cold-worked tools must be quenched so as to produce primary hardness (Table 1).

     
  2. 2.

    The size of the actual austenite grain coupled with hardness can be used as a criterion for the quality of the heat treatment of tool steels. The grain size must be determined with a magnification of 500.

     
  3. 3.

    It is advisable to amend and add a further section to the GOST 5639-51 State Standards on detection of the true austenite grain boundaries in steels which have a martensite structure after quenching.
