52100 examination

I'd be curious to see these results with medium speed oil and the annealed stock with a 5/10 min increase in soak time.

I like the way you think! I have 5 gallons of Mc-Master Carr 11 second oil on its way.
Too bad I already cycled to rest of the bar that I had. I'd like to redo all the testing using the 11 second oil.

I meant to post this a while back but forgot. There is another source of 52100 in our little community. Ray Kirk sells round bar in several sizes and he has at least two formulations. His big `1.75 inch bars have like .93% carbon but the .531 inch round that he sourced in Dahlonega, Georgia and uses for his little Traii of Tears blades has a carbon content of 1.01%.

Ray Kirk from Oklahoma? Thats crazy, I just met him and joined the Knife Group Assoc. of Oklahoma. In fact I just got an email from him this morning inviting me to a shop tour next month!

I’ve used the McMaster Carr quench on 52100 many times. I get good hardness numbers from it. I used on Aldo’s 52100 and regularly got 66rc..It’s good oil.

It works fine but it is ugly if you are used to #50. Lol
