Hello and good day, I have been planning on adding "cryo" Liquid nitrogen quench to my Heat Treat line up.. With the addition of stainless steel to my current offerings. So this is the next step to make sure the SS steels have the proper RC and toughness. As well as edge retention.
[/FONT]Based off my limited experiance with this cryo treatment. I dont think it makes and significant difference with to my current carbon damascus mix. And if I understand correctly the SUB ZERO treatment benefits most stainless steels. With a notable gain toughness as well as additional hardness and edge retention. We have also started making a new damascus combination, of O1 an L-6. Which if I understand correctly will benefit from being Cryo quenched..
[/FONT]I have spent some time researching this and found a couple of great options for my new cryo tank. As well as tons of info on the subject on line. I talked to another knife maker that I have much respect for. He was very kind and open, sharing some important info with me so I make a informed purchase on the storage tank. He is currently doing cryo and has done much testing on many of the NEW SS steels. I gained more info from 1 phone call then I did searching the internet for 15 hours reading on the forums. So I need to say THANKS!!!! you know who you are. I appreciate your time and advise.
This is gona be fun!!
This is a obsession, As most of you know. Proper Heat Treating is just as important as the steel type.. If not even more important! As a maker, I am always trying to refine my process and testing.. and learning.. There is room for improvement, and I intend to find it. This is the next step in my evolution. I know there are some here that have much more experience with this, and I welcome your comments and hope to learn as much as possible about this process B4 the new Dewar arrives.. Im just opening the door on the subject and starting to learn.. So please share your experience.
[/FONT]Selecting the right tank turned out to be the easy part. The hard part was finding it at a good price! The price for a new tank was WAY out of my reach. So the search continued. Ebay and Craigs list, all the forums etc.etc. I finally found my tank.. A used 34L tank with a neck tube opening of over 3.5" For the TALL kitchen knife blades and large choppers!
[/FONT]The LN tank is on its way to me and Im jazzed! Thanks to EVERYONE who gave me some help and advise, I hope to one day be able to return the favor or share or help someone else by passing along the same advise and info!
[/FONT]God Bless
