Confirmation on Spring Tempering D2

[David Schott]

Hello,
Im making up some slipjoints in D2 and am having trouble finding charts on spring tempering D2. I'll be hardening from about 1825 and tempering at either 475 or around 950-900 for the blade, but I cannot seem to find a chart on achieving spring temper for the backspring.

Am i looking right at charts thinking that 1150-1200 will yield a spring temper on D2?

Heres the chart Im looking at thats gauged mainly at RA but has D2 hardness as a function of temp.

That gives me tempering temp for blades, but I need to know tempering for spring hardness to make the backspring on a slipjoint. Blade hardness will snap. I know its out there but its hard searcing for "D2" on any forums because its only 2 letters long, haha

For A-2 I temper at 1050 for 2, two hour cycles. I let the spring cool between cycles.

Look at the chart mid way down the page it gives spring tempering for most blade steels
