Amada Punch Tool Steel?

We use Amada Turret punching machines here at work and I was wondering what type of steel is used? The Wilson Tool Co website calls the tooling steel some goofy trade name but does not list actual type of steel used? Reason I ask is that we have all kinds of broken punches and dies that might be good for forging but not sure what type of steel they might be? Any ideas? Thanks all! Don
 
It all depends on the style. I know Vortec series tooling is M2 standard.

I just put a call into my tooling guy. I'll post more if I find anything out.
 
Awesome! We break tooling all the time, well not all the time, but we have 3 turrets and tooling does wear out and break! We throw it in the scrap bin!
 
Personally I wouldn't want to make a knife from a piece of tool steel that has broken due to hard use. Good chance that there are other nasties hidden that might come back and haunt you later. I might make punches, hardies, hot sets and stuff like that tho - all the while knowing that they might fail at an inopportune time.

these punches include a full sized body, round, with the ends machined down to make certain shapes. They wear out and need to be sharpened. You only have so much tool life before they run out of useable height. Also even if they break it is more of a chip, and it mostly does not leave the tool tip. See Below tool tip circled.

Gotcha, anything proximal of the reduced section should be good to go. In that case it's a nice source of material, except for the problems of annealing air hardening steel.
 
the forging punches we use for warm forming are H10 or H13; very good toughness and hot hardness, but usually 55 hrc or less. cold form punches are H13 or M2, again hardened to low 50s and too big to play with.
