I've been wanting to try some 52100 but only have 11 second oil. Will this work? What is the best quench speed for 52100? Thanks in advance for any and all input.

I don't know if this answeres your question exactly but the ITT diagram that I have for 52100 gives a little more than 2 seconds to get the temperature from Ae1, which is listed as about 1350 degrees F. to get it under the nose of the curve at about 1100 degrees. It looks like Ms is about 490 degrees. The blades that I have made with 52100 have been austempered in peanut oil at 425-430 degrees for one hour which looks like it should produce an HRC of about 58-59 with a mixture of bainite and martensite.
