In another thread someone (I think Kevin Cashen, who has more metallurgy in his pinky than I'll ever have) stated that normalizing 1095 should be done starting at 1500°F or above. Then a few more cycles at lower temps, although he didn't give exact data in that post as to what the lower temps should be or exactly how many cycles. He then stated that if you want to spheroidize it, quench after the last normalizing cycle and then temper at 1300-1325°F, but didn't specify for how long (assume an hour?).

I hope that gets you in the ballpark for what you were looking for. FWIW, I made some good knives cavemanning 1095, but after hearing Kevin and others wax eloquently about metallurgy, it's clear to me that precision heat, soak times, etc etc will make this steel even better, just like O1.

Thanks Dan!

no problem
I was playing yesterday and tempered ( no quench yet) 13 blade blanks of 1095 hot roll that I had jetted out,
tempering at at 900F to make it more workable,
they should be at about 41RC right now
I wanted it workable and controllable without any decarb
we'll see how that works for me
I may work it up to 1200F playing with the differences in workability
