Heat Treatment of Cr Moly steel parts
what i can understand from cementation hardening is the hardening induced in the steel due to formation of cementite.
Since Cr and Moly both are good carbide formers so the amount of carbide formed in the steel will account for the hardening in the steel.
I (personally) would not quench such steels due to danger of cracks.
ps: I am a student and donot have any authority over metallurgy rather iam trying to understand the subject.
I would appreciate your comments on my reply given.
