I have this posted on another forum but hopefully you all can help as well
EditReporthave a heat treat oven on order. I want to start out with oil that will get me the best results but I would like to use just one type of oil. From what I have read Parks # 50 and AAA are often used. Parks 50 seemed to be used the most. So what Carbon steels can be used with #50 and what steels need AAA? I have 52100 and 80crv2 And have used 15n20. I won’t be HT a lot of blades at a time just a few. I would like to try W2 and 26c3 in the future. Is a one gal tank enough of oil to do 2 or 3 blades at a time Before the oil gets to hot?
Also do you guys use your HT oven to temper?
