D2 Steel

[watakipoma]

I obtained some stock of D2 steel.

I was wondering what would be the best way to work this steel...

Countless hours at the grinder or forging it?

That is my favorite for stock removal.

Countless hours at the grinder

I mostly stock Grind...
you need a bigger grinder
if you're taking more than 1 hour on most any blade
from profile up to heat treat.

I had a couple of planer blades that I believe were D-2. I just wanted to bend the ends dowm to make handles for a draw knife (a wood working tool). Everything was fine until I dropped one after bending it and it broke like glass.
If I do this again, that is just to grind off enough to make the handle ends and heat to bend, can I temper just the bends? What color would be best? I kept the body of the blade cool, BTW.
Thanks, Lynn

planer blades are heat treated fairly hard so you should
draw it back more to soften it up a little more like a knife,,
and at the bends and out where you wouldn't use as an edge
these should be drawn back to at least spring temper, at about 1200 deg.

Thanks for the reply, Dan. I'll try dark blue for the tempering.

Dark blue is going to be around 700 deg,,
but not always..
