Tool steel 1.2379 or 1.2842 for bending stress on dies
(OP)
Hi all
Which of the above mentioned tool steels are better for cold formimg dies that will be under bending stress? The bending stress is caused by a punch that leans on a part of lower die to deform the piece. What would be the considerations in heat treatment of both?

All forming tooling is a balance between toughness and wear resistance.
You need a good handbook on tool steels that compares properties and various heat treatments.

If your punch has any lateral loads in it then you need to redesign you tooling.

and please introduce me some great tool steel handbooks

Or if you need even better toughness, CPM 1V would be an excellent alternative choice:

Both grades are currently manufactured by Latrobe steel, a subdivision of Carpenter Technologies.

If you want to stick with a conventional tool steel then select one for toughness such as H13, S7, or L6 and then use a surface treatment (nitrocarburize) if you need better wear resistance.
