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.

With some luck they can provide you with a substanciated answer. If you do, you can post the result as an answer to your own question. That helps future users who have the same question and is very much appreciated. – Elmy May 13 at 10:38
  • Are you forging the steel or just shaping it? From what I have seen it is an involved process to make a forged steel knife with the repeated heating and quenching and hammering and so on... very different from industrial finishing of metal products. – rebusB May 14 at 17:50
  • Check out this link as it goes into the science of quenching and may provide some answers...Gas Quenching - an overview... – rebusB May 14 at 17:55
  • The blade not be forged, just cut to shape from a piece of steel – Valentin Virban May 15 at 18:08
