The vtoku2 core steel is a water quench steel, i want to water quench it to maximize the minimization of RA :D
but im afraid of the stainless cladding wanting to split the core apart. HAs anyone done this? Its kind of expensive steel, im hesitant to just go for it.
 
I have had it split down the middle in a Parks #50 quench. I would not suggest water.
 
I've made a handful of the VT2 san mai blades using P50 as a quench without issue. Like Stacy, I would not suggest water.
 
Any issues with split cores in the p50? Had you done any bevel grinding or forging to upset the pattern before quench?
 
Is this the Takefu prelaminated? You said it is a water quench steel, How do you know this? Do you have a spec sheet from them? What does the spec sheet advise?

I have water quenched other Takefu laminated many times. There’s no problem with splitting.

Edit - I just looked it up and Water is specified so I would definitely go for it
 
I never used water for Vtoku2 but you need to be fast from the oven to the oil.

With such an expensive steel I would rather go with the much safer bet which in this case is fast oil...
 
Thanks for your responses.
I do have 2 gallons of parks 50 but i am intrigued by the water quench possibility. One of the graphs in Larrins book was showing a better RA conversion with water. Im not sure that would be noticeable in performance.
I am going to try this though, first on a coupon that is not pre ground in any way and then also on a pre ground and upset coupon. I do plan to round and finish all edges to 220 grit, that seemed to help with my water quenched 26c3 stuff.
