Compressed air as a cooling medium in induction hardening

Theory

Conclusions

  1. 1.

    In induction hardening the cooling rates from 650 to 550°C and in the region of the martensitic transformation of supercooled austenite are of greater importance in quenching with compressed air than in quenching with still oil.

     
  2. 2.

    The cooling rate is nearly the same in quenching with oil and compressed air.
