I have been making knives as a hobby mostly for myself and friends for some time now. I have been using mostly carbon steels such as UHB20C/1095, O1, 5160. I want to step up my game with more exotic steels such as AEB-L, RWL-34, ELMAX, D2 and N690Co.
Due to lack of dedicated equipment I found a Steel Heat Treatment company that will help me with quenching, cryo, and tempering. The only problem is that they only offer 'pressurised nitrogen quenching'.
Could you please tell me which of the stainless steels above can be quenched this way?
I could not find any information on Bohler and Uddeholm websites regarding this method.
