1080 clay quench help

Doug and Kevin, thank you so much. I will be sure to look that material up. I am becoming fascinated with steel lately, my wife thinks I'm weird(er).

Let me fire this one out there for you guys. Kevin, you are going to HATE this!!!! If you were making a knife (with all consideration towards the edge and edge retention, not toughness), out of Cru Forge V or 52100, or the 1.2519 I have on the way, and the steel has been properly normalized at temp and time, what austenitizing temperature would YOU choose, and why? 1475-1500 or 1525-1550. You have no idea how this is racking my brain (pea-brain). I will literaly wake up in the middle of the night with this question bearing down on me.
 
OK, I think I answered my own question. I just downloaded the book Metallurgy for non metalurgist by John Verhoeven. Awesome material. In looking at a simple phase diagram, a steel with carbon content of 1.15%, in order to get it to austenite, it needs to be around 1550. So simple, I think.
