52100 heat treating trouble

It definitely got overheated at some point!  For 52100 I use four or five normalizing cycles and no soak at all after forging.  For quenching I may let it soak for one minute once it's at heat, but usually not.

Others may not agree but I like to cool to black and check the blade with a magnet to be sure that phase change has occurred  before returning the steel to the forge.. The magnet should stick to the steel.

What temperature did you quench this at?

52100 has been my steel of choice last few years
