Flame Hardening and Quench Time
Flame Hardening and Quench Time
(OP)
I am flame hardening 4150 steel that is being quenched in oil and then tempered in an oven. My question is does it matter how long the parts remain in the quench oil, or is there a recomended temperature that the parts should not fall below before they are taken out of the quench oil?
