Conclusions

  1. 1.

    As a structural criterion in nondestructive testing of the quality of hardening and tempering of parts of 58 (55PP) and 47GT steels on the basis of magnetic properties the selection of the excess ferrite content in the structure of the steel is recommended.

  2. 2.

    With the use of the recommended structural criterion the most reliable results for inspection of steel parts may be obtained with selection of magnetic permeability as the inspection characteristic.
