Queen ACSB blade steel

Post by Casecase »

Hello all!
Just a quick question. Queen ACSBs have D-1 Tool Steel blades, PH hardened. Is this a process (found it online via Wickipedia) or a company that performs it? Just curious. (None of us are as smart as ALL of us!)

Thanks!

PH is the folks that heat treat the D2. I either never knew or don't remember what PH stands for.

....i think PH means "precipitation hardened", which i think means it is quenched in water, rather than oil(OH)........... ::shrug:: ........
