Conclusions

  1. 1.

    After tempering at 600±10°C 6h steel 20KhN3MFA is satisfactorily machinable, and this tempering regime can therefore be recommended as preliminary heat treatment prior to machining.

     
  2. 2.

    A rapid method of determining the relative machinability of steel and alloys was suggested.
