D2 and folder spring

[JDW]

I am planning a folding hunter. I will be using D2 for the blade. Does anyone use D2 for the back spring on folders? And what would the target RC be? Crucible D2 data sheet shows 1000 degree temper temp gets a RC of 55 is that still to hard for a good spring? I was thinking in the 45-50 range. Crucible also says to temper between 400 and 1000 degrees, so 55 is as low as I can get.

Dale,
45-50 is what you want. I've used D-2 for springs and it works as good as anything.
