hello, maybe some of you remember this (on this very forum):

If i need to go stainless i would go for AEB-L, 13c26razor or alike.
Assure protection for balde surface
1st preheat: 500-600°C, equalize
2nd preheat:800-900°C, equalize
Autenize: 1050-1060°C, equalize, soak 12-15min
Quench in Oil preheated 60-80°C
Cryo: immediately after cleaning, minimum -80°C or lower soak 30min
1st Temper: 150°C equalize, soak 2hrs, quench in water
Cryo: immediately after temper, minimum -80°C or lower soak 30min
2nd Temper: 180-200°C equalize, soak 2hrs
should give you 60+ and a fine durable grain.

This is what i would do."

Also same indications, but different austemp and time I was founded on an German forum still from Roman and it was:
Autenize: 1065°C, equalize 3-5min, soak 5-8min
everything else is the same.

About quenching in oil, most people who care about the results use an antiscale liquid compound Condursal 1100Z that assure protection up to 1100°C and the contact of the blade with the oil is optimal.

According to verhoeven that recipe without subzero should give 62...
Most of our's not to reason why, but to control heat or die... ;-)
