Hi,
I'm receiving heat treatment furnace so get the ability to do bit more complicated heat treatments what torch can't do. My question is about heat treating 17-4ph to H 900 condition. From the spec sheets I have found that it needs to be kept in 900F for one hour and air cooled. Does this mean that after one hour take it out from the furnace and leave it to room temperature to cool down? Or does it matter how slowly it will cool down, eg. can I leave it into the furnace for cool down overnight and take it out next morning? I assume this is not ok..
Thank you in advance
