i have a large block of cpm 3v. its 1.53" thick by 7.125 by 7.125. im thinking of cutting it into forging stock. what would be a good thickness of strips to cut off this. im taking it to work and am going to use the huge liquid cooled automated bandsaw. thanks everyone
 
Well. What's usually the thickness of the knives you make?
 
Forging stock? Have fun! :D Don't use any tools you like, it may dent them...

That said, it's not impossible, but make sure you're in the right temperature range for forging. Crucible's data sheets should give you that. Just test with a hammer other than your favorite. I've heard that CPM1v can and will dent an anvil/hammer. I can't imagine what forging 3v would be like!

Don't forget to take pictures :)

Slice it into 3/4" slabs and make some short bladed integrals. I would rather spend some time with a 36 grit belt on that stuff than even consider forging it. My hammers aren't expensive but I have come to like them. Make grinding stock not forging stock:)
 
You can slice that up like a loaf of bread in a band saw.

You can jb weld it to an aluminum plate (to hold it and keep things square) and feed it through your big bandsaw in 3/16" intervals. I recently sliced up a really large bar of 6-6-4 titanium this way. You can pop the aluminum off after the cuts.



I don't know. It seams a waste to forge a CPM steel. On of the up shots of CPM is the fine carbide structure. Once it is up to forging heat those carbides are going to join together some.
 
ya i gess your right about the forging of cpm steel, im not going to gain anything just increse my chances of a mess up. im going cut some thick chunks and then the rest into 3/16 slices. and we have a surface grinder to :D
