I recently came into possession of some AEB-L steel and I have some questions regarding the heat treat of this steel. My first question is about the initial ramp to 1560°F and equalize step. Can I start the heat treat with the knives in the oven or do I put the knives in once the oven reaches 1560° F? How long will I need to hold at that temp to equalize? I have read that this metal can be cryo treated with dry ice and does not need a soak but to bring the metal to -95°F and then temper twice at 2 hrs each. How long should the knife soak in the dry ice mixture (91% ISO Alcohol and dry ice)? And lastly, do I need to cryo treat between each temper cycle? I have read this in only one of the articles but thought it would be worth asking.
Thank you for your time!
