I have looked and not found an answer or suggestion on this subject.......
I normally lay the blank on top of my gas forge while it heats up, blank may get to 80-90 degrees depending on weather. Once the forge has been running 5-6 minutes I put the blank in and do the heat treat.
On tempering I just stick the HT'd blank into the oven and let it warm up with the oven.
Question- Is it better to let the blank heat up with the forge or stick it in at high temp. I have always felt jamming a cold blank into a hot forge could cause stress cracks but letting it warm up with the forge could cause a over heat problem.
Same as for the tempering oven, though it is a way lower temperature overall. What are your thoughts on this and how do you handle this issue?
