I heat treated a blade two nights ago. Well then I put it into the oven for what I think was a 400 degrees oven for 90 minutes. Then about halfway through the second temper, I fell asleep. Someone took it out of the oven. My question is...if I try to give it a 90 minute temper now is it too late? Or can I still temper it one more time?
 
If they took it out sometime after it had been in for 90 minutes you're fine as is. Too
long tempers don't hurt much at all.

You can certainly temper it a third time if you wish. It won't hurt.
 
Thanks I'll throw it back in for another cylcle as I was so tired (and took benydryll) for my allergies. I can't. Be certain. Thanks for your reply sir.:thumbup:
