Hi,
I am about ready to heat treat my first knives! Since I melted my homebuilt oven down, I will do it at work. At work, we have two ovens. They were both just recalibrated, and will work great. I plan on making a rack and doing four blades all at once. Blades are o-1 tool steel that I will bring to 1475 degrees, for 10 minutes and quench in about 140 degree oil. Don't have the real quenching oil, so will have to use something else. What oil would work best.
I will let them cool to 125 degrees, and temper for two hours at (not sure) degrees. What do you recommend? I will than let them cool to room temperature, and temper again. What do I want on the rockwell? We do have a rockwell tester.
We also have stainless foil, Is the extra expence worth it?
This is my first time doing something like this. I just want to get it right. Don't want to see all my work go down the drain!
Any changes to my recipe or advice would be much appreciated.
Thanks in advance!!!
Dave
