Grain size

I think you might of mis read the data at AKS. Here is a screen shot of it and it does not say to do both it says if you use the 1940° austenitize temp then you soak for 15min. BUT if you use the higher 1975° austenitize then you only soak for 5min. It is not saying to do both its two separate heat treat formulas.

Sorry, I got a little confused. The double quench I'm talking about was recommended by Devin T. and it's a prequench at 1725. Then on up to austenitize temp.
