Thank you for your suggestions.
Cycle followed now is 1600 F -20 min- Mar quenching @ 240 -40 minutes.
Tried 1550 F -5 min-Mar quenching @ 240 -40 minutes, But did not find any improvement.
I will try cycles suggested by you & let you know.
Thank you very much. Material in consideration is SAE 52100. I am facing brittleness after heat treatment.
Could you please suggest an appropriate cycle.
When you heat treat ( hardening & tempering)a steel which was spherodized annealed before cold working,
do you follow the same heat treatment cycle as you would do in case of non-spherodized annealed steel of
the same grade of steel , or is it different?
