annealing 4140 - practicalmachinist.com
Thread: annealing 4140. I agree with John that the hardness sounds too high for 4140. In an oil quench about 55-57 is what I've always gotten from it. Of course it could have also been cased and then it would easily go to 60+ at the surface. Unless there's some reason for a full anneal, the safest thing to do is a subcritical anneal.
