Odd question about S35vn heat treat.

[Grayzer86]

This may be a stupid question, but I am going to ask it anyway. I know most guys are running a HT on their S35vn with the same program as CPM154. I regularly use CPM154 so that isn’t an issue. I also use quite a bit of AEB-L. For the AEB-L, I use the program suggested by Devin Thomas, with the 1725 prequench. My issue is that I have 14 blades ready to heat treat, 12 in AEB-L, and 2 in S35vn. Normally for my 154, I put the blades in the kiln and run the program starting from a cold oven. What I am wondering is, would it have a negative effect on these two if I did not run the preheat cycle? I was basically wondering if I could put them in the oven during my 1725 cycles and let them come up from there to 1975 with the other blades. I only have one kiln, and because I have to drive 190 miles to get dry ice, (yes you read that right) I was hoping to be able to do them all in one night. If the S35vn blades need to come up from room temp and have the 1450 hold and equalize, before climbing to target temp, then that’s what I will do, but I figured I would ask those around here with more knowledge than me. My thinking was that they would be able to get their soak time in also while I was quenching the AEB-L blades. My main concern was that if I can’t do them together like that, it would have to be done a different day because there is no way the kiln will come down enough to start a new program the same night.
