heat treat
Hey guys figured i would post a new thread since the last one has turned into a book...anyway i was away for a few days and since i been back i have been coming up with a few designs as ''prototypes" that if they work out well ill make a few more and sell them...people already asking me for a while and i feel combtorable taking someones money now so anyway i was HTing them yesterday the liquid nitrogen over night now tempering everything....i may have run into a problem maybe not? i put the blades in the even heat oven at 350 well i checked on it a min or 2 later and it was all the way up to 381 it immediately started going down but i have never seed the oven go so far above the set temp it may varry a few degrees but never seen it that off....do you guys think this will have a big effect on the temper or maybe not since it was only for a min? ohh its 440c steel
