pitting in ATS-34

I'd say oxygen getting to it, combined with contamination of surface.
Make sure you clean the blades before they go into the SSEnvelope
or whatever protection you use (PBC Special and Turco spray are two
other choices for home treating, industrials houses pump oxy out of oven
and replace it with inert gases).
Acetone, Denat Alcohol, followed by wash in soapy water should get blades
nice and clean. Make sure water forms a nice even layer over steal (CLEAN) and doesn't bead up instead (DIRTY).

Oh ... be UBER careful with Turco ! I bought darn thing a looong while back. Tried it once (applied with a brush to a cleaned blade) and it caused just disasterous pitting too !
Could never figure out how to remove it after HT. In contrast, PBC comes off during quench and whatever is left can be easily removed with hot water.
People that reported having luck with Turco dilute it, 5:1 or so and _spray_ it on. HF sells those refillable aerosol bottles that might work w/o having to crank up your air compressor every time.

Turco is for carbon blades and Ht blow 1550F. If you use it on a stainless blade at 1950 it will turn to pure borax and then eat right into your blade.
Several years ago I told someone to try Turco for HT.I missed that they were doing a stainless blade.BAD ADVISE!
So to clear up any misunderstanding - DO NOT USE TURCO ABOVE 1550F.
