Tempering Temp of NJ Steel Baron 440C?

[SamaraVolk]

I've researched this topic extensively. I'm cryoing some 440c blades now and have found a number of different graphs/opinions on the tempering temp for this steel. They range from 200f to 400f. I know suppliers have their own data sheets but this range makes it difficult to choose a curve. Alpha knife supply and USA Knife Maker/Kovak knives (from the Evenheat website) differ a lot. Any thoughts?

for 440C I always go with Bohler N695 datasheet, can't go wrong.
