First of all, I would like to say that my knowledge in the area of heat treating is very limited. I primarily make knives by the stock removal method and maiinly use "stainless" steels such as 440C, 154CM and 440V. I am a part time knife maker and thoroughly enjoy the craft.
I send all of my blades out for heat treating and every thing that I have seen or read indicates that 440C and 154CM (or ATS34) should go through a sub zero freeze to -100 F. The place where I send I my blades does not do this as a standard practice. This concerns me somewhat since I am really not sure if this is necessary or not but as stated before, everything that I have seen on the subject indicates that doing this may be the standard procedure or industry standard.
This same company does offers cryogenic treating as well and the steel is taken down to -300 degress and held there for several hours. Would this accomplish the same thing? This would be at an additional charge of course.
I just want to provide the best product possible to my customers. Any comments or advice would be greatly appreciated.
