Oct 14, 2016 · In reality people temper 420 either 500-600F, or 1000-1100F. The size changes in 17-4 (or any PH) when you age is known and very predictable and repeatable. It is much easier to machine a PH grad in the annealed ( A or T condition) and then final age, than trying to machine 420 fully hardened.
